exercise 5. part 1 - surface to solid

In this exercise, topographical data points were downloaded from the NASA Shuttle Radar Topography Mission (SRTM) database and translated into a digital surface. Then, this surface was put into a grasshopper definition which extruded the surface from a given plane in order to generate a solid. This solid was milled on the CNC router through a materially reductive method, in which an instruction set consisting of coordinates (generated through RhinoCAM) informed the mill’s path to cut away material from the solid block of 20″x 20″x 3″ laminated wood. This study prompts attentiveness toward the implications of relative scale throughout all stages of design and fabrication processes, both how scale functions as a generator of unknown variability and as design tool.

selection of topography - scale of earth v. scale of the product, earth’s surface is actually very flat relative to size of sphere on which it sits. This flatness reads even at the scale of a single latitude-longitude swatch of extracted data points (NASA Shuttle Radar Topography Mission). In order to combat this scale and define an area in the lat-long that had appropriately variable elevation, the area extracted for the surface had to be reduced to 1:100 of the original area.

adjustment of parameters of gh determined solid - once the data points had been translated into a surface using the first grasshopper (gh) definition, the baked surface that came as a result was input into the new “chunky surface” definition in order to generate the solid. At this point, various adjustments to parameters within the gh definition such as min/max count, aspect ratio, or even a surface rebuild (not within the gh definition, but rather command within rhino onto the surface) all yielded variable conditions of the base unit, or the smallest flat element within the larger topography. Object 1 has many large, rectangular units as a result of a long series of arbitrary aesthetic adjustments, which equates to lower fidelity to the variability within the original surface and a more abstracted reading. Object 2 was not subjected to any parameter changes, and therefore exhibited much smaller and more square elementary units that were able to accommodate the true topography more accurately.

translation render-to-mill - in this final step, the implications of tool capabilities and limitations were made very apparent. On object 1, the size of the milled object, though it looks much less complex and of lower variability than object 2, took much longer to mill (3 hours opposed to 30 min) due to the fact that it was 2.5x the length and width of object 2. This is of practical consideration when constructing multi-step and piece models in which material efficiency/cost and time/labor costs are of relevance. In fact, it was due to time/labor constraints that the decision was made to mill object 2 at the smaller size. This resulted in some movement of the block during the milling process, as the shear forces were strong enough to begin to dislodge the form from its constraints (small blocks visible in fig. 8). Additionally, for object 1, the angle of approach of the end mill was set to 45 degrees for the finishing portion of the job (versus 30 degrees for object 2). This angle, accompanied by the low relative depth of each unit to those surrounding compared to its surface area might have been the cause for some of the shearing forces that delaminated some of the object’s top layers (visible in fig. 9, large flat space in bottom right corner of object 1). On the other hand, the large elementary units paired well with the .5 inch end-mill, in that the corner moments, though still rounded in actuality, look very angular at the scale of the unit whole. In contrast, on object 2, due to the fact that the elementary unit was about .5″x.5″, the reading of this corner bevel resulted in a much more jagged and organic looking finish. The scalloping and sometimes fully circular moments on the final product inadvertently begin to allude to the mountainous nature from which this solid was derived, all due to a matter of relative scales.

The milled objects hold some connection to the following systems example in Deplazes: Shin Takasuga’s Railway Sleeper House. “The universal utilisation of one single type of construction element for the whole structure – walls, floors, columns, roof structure, the built-in furniture too” (106) of the house allows it to read as a sort of natural extension of the forested topography of Miyake island, on which it is situated. Further blurring lines between landscape and building, “in the Railway SleeperHouse we can identify a subtractive design principle: the rooms seem to have been hacked out of a closed, cruciform stack with a rigid outer shape”. Similarly, the raw materials rely on the subtractive quality of the milling process to reveal the varied 'stacked’ surface conditions. One might even begin to reimagine the above exercise objects to some human scale, as containing qualities among its ridges and folds, where ridges begin to read as semi-hollow surfaces and platforms with habitable internal structure.

How Did We Get Here? The History of BIM Service Providers in USA

Keywords: BIM services, BIM consulting companies, BIM service providers in USA, BIM consulting services.

The concept of BIM has existed since the 1970s. The first software tools developed for modelling buildings emerged in the late 1970s and early 1980s, and included workstation products such as Chuck Eastman's Building Description System and GLIDE, RUCAPS, Sonata, Reflex and Gable 4D Series.

The two main methods of displaying and recording shape information that began to appear in the 1970s and 1980s were constructive solid geometry (CSG) and boundary representation (brep). The CSG system uses a series of primitive shapes that can be either solids or voids, so that the shapes can combine and intersect, subtract or combine to create the appearance of more complex shapes. This development is especially important in representing architecture as penetrations and subtractions are common procedures in design, (windows, and doors).

Database Building Design

Seeing buildings through the lens of the database contributed to the breakdown of architecture into its constituent components, necessitating a literal taxonomy of a buildings constituent parts. One of the first projects to successfully create a building database was the Building Description System (BDS) which was the first software to describe individual library elements which can be retrieved and added to a model. This program uses a graphical user interface, orthographic and perspective views and a sortable database that allows the user to retrieve information categorically by attributes including material type and supplier.

In the early 1980′s there were several systems developed in England that gained traction and were applied to constructed projects. These include GDS, EdCAAD, Cedar, RUCAPS, Sonata and Reflex. The RUCAPS software System developed by GMW Computers in 1986 was the first program to use the concept of temporal phasing of construction processes and was used to assist in the phased construction of Heathrow Airport’s Terminal three (Laiserin – History of BIM). The founding of the Center for Integrated Facility Engineering (CIFE) at Stanford in 1988 by Paul Teicholz marks another landmark in the development of BIM as this created a wellspring of PhD students and industry collaborations to further the development of ‘four-dimensional’ building models with time attributes for construction. This marks an important point where two trends in the development of BIM technology would split and develop over the next two decades. On one side, the development of specialized tools for multiple disciplines to serve the construction industry and improve efficiency in construction. On the other side is the treatment of the BIM model as a prototype that could be tested and simulated against performance criteria.

A later but prominent example of a simulation tool that gave feedback and ‘suggested’ solutions based on a model is the Building Design Advisor, developed in 1993. This software utilizes an object model of a building and its context to perform simulations. The program includes basic optimization assistants to make decisions based on a range of criteria which are stored in sets called ‘Solutions’.

Virtual Building

While the developments were happening rapidly in the United States, the Soviet Block had two programming geniuses who would end up defining the BIM market as it is known today. ArchiCAD developed in 1982. Using similar technology as the Building Description System, the software Radar CH was released in 1984 for the Apple Lisa Operating System. This later became ArchiCAD, which makes ArchiCAD the first BIM software that was made available on a personal computer.

ArchiCAD has made substantial gains in user base from 2007-2011, mainly as a tool for developing residential and small commercial projects in Europe. Recent improvements have made ArchiCAD a major player in the market though fundamental issues such as a lack of a phasing component and a complicated (but flexible) programming environment for its family components using GDL (Geometric Description Language) To date, Graphisoft claims that more than 1,000,000 projects worldwide have been designed using ArchiCAD.

Not long after Graphisoft began to sell the first seats of Radar CH, Parametric Technology Corporation (PTC) was founded in 1985 and released the first version of Pro/ENGINEER in 1988. This is a mechanical CAD program that is utilizes a constraint based parametric modeling engine.

By 2000 the company had developed a program called ‘Revit’, a made up word that is meant to imply revision and speed, which was written in C++ and utilized a parametric change engine, made possible through object oriented programming. In 2002, Autodesk purchased the company and began to heavily promote the software in competition with its own object-based software ‘Architectural Desktop’.

Revit revolutionized the world of Building Information Modeling by creating a platform that utilized a visual programming environment for creating parametric families and allowing for a time attribute to be added to a component to allow a ‘fourth-dimension’ of time to be associated with the building model. This enables contractors to generate construction schedules based on the BIM models and simulate the construction process.

Towards a Collaborative Architecture

There has been a trend towards the compositing of architectural files with those of engineers who create the systems to support them which has become more prevalent within the past seven years as Autodesk has released versions of Revit specifically for Structural and Mechanical engineers. This feature released in Revit 6 in 2004, enables large teams of architects and engineers to work on one integrated model, a form of collaborative software. There are now several firms working towards visualization of BIM models in the field using augmented reality.

To combat any inefficiency the International Foundation Class (IFC) file format was developed in 1995 and has continued to adapt to allow the exchange of data from one BIM program to another. This effort has been augmented by the development of viewing software such as Navisworks which is solely designed to coordinate across varying file formats.

Following in the footsteps of the Building Design Advisor, simulation programs such as Ecotect, Energy Plus, IES and Green Building Studio allow the BIM model to be imported directly and results to be gathered from simulations. Autodesk, through their growth and acquisition of a broad variety of software related to BIM have contributed to the expansion of what is possible from analysis of a model. In late November 2012, the development of format, an application that allows the conceptual beginnings of a BIM model to be started on a mobile device is a leap for the company.

Contemporary Practice and Design Academics

Some have taken a negative stance on BIM and parametric as they assume so much about the design process and limit any work produced to the user’s knowledge of the program. This can enable a novice designer who has learned how to perform basic commands to become an incredibly prolific producer while a highly educated and experienced architect can be crippled from inexperience with a programs interface or underlying concepts. This creates a potential for a generational break line that becomes harsher as a new technology gains market parity.

Some BIM platforms that have a small market share but have made big impacts on the world of design include Generative Components (GC), developed by Bentley Systems in 2003. The GC system is focused on parametric flexibility and sculpting geometry and supports NURBS surfaces. The interface hinges on a node-based scripting environment that is similar to Grasshopper to generate forms.

Parametricism can only exist via sophisticated parametric techniques. Finally, computationally advanced design techniques like scripting (in Mel-script or Rhino-script) and parametric modeling (with tools like GC or DP) are becoming a pervasive reality. Today it is impossible to compete within the contemporary avant-garde scene without mastering these techniques.”

Since these techniques have become increasingly complex there has become a component of architectural schools which is specified to train in specific software. The programmer takes an idea of what is commonsense and simulates a workflow using tools available to them to create an idealized goal. In the case of BIM tools, the building is represented as components including walls, roofs, floors, windows, columns, etc. These components have pre-defined rules or constraints which help them perform their respective tasks.

BIM platforms typically represent walls as objects with layers, these layers are defined in terms of the depth and height of a wall and are extruded along the length of a line. The program then has the ability to calculate the volume of material contained within the wall assembly and to create wall sections and details easily. This type of workflow is based on the existing building stock and common industry standards and therefore a project which is produced in a BIM platform which emphasizes these tools is likely to reinforce existing paradigms rather than develop new ones. Additionally, the programmers who worked on the early BIM platforms often did not have a background in architecture but employed hybrid architect/programmers who contributed to the development of the programs. One notable exception I have found to this is the work of Charles Eastman who received a Masters of Architecture from Berkeley before working on the Building Description System. The roots of the major BIM platforms that are in use today have been developed by programmers with the peripheral input of hybrid programmer/architects and a global user base who contributes to the development of the software via ‘wish lists’ or online forums where grievances can be aired about a product workflow. The grievances typically result in new features and build upon the existing interface.

Though the general concept and technology behind BIM services is approaching its thirtieth anniversary, the industry has only begun to realize the potential benefits of Building Information Models. As we reach a point where a majority of buildings are being crafted digitally, an existing building marketplace where building materials and structural components can be bought and sold locally will emerge.

Project 2, Stage 2 Surface Detail Problems

Of course since all of the previous stages of making my master model were problematic this stage had to be too.

As a test piece I set up a Voronoi pattern to project onto the top surface of the orthotic.

Typically this is done by creating a flat pattern and using surface morph to project this onto the surface however this wasn’t working and I couldn’t find any solutions that would get it to work.

I found another strategy to achieve similar results using the map to surface tool.

After a lot of messing around to get it to work it did project the pattern down to the surface, however it was always over-sized. I tried various solutions and data culling strategies to try to fix this to no avail.

I didn’t just want to project the flat pattern straight down onto the surface because I was worried at how this would deal with the near vertical side and back walls of the orthotic, but after no other solution worked I had to just go with projection.

It gave a surprisingly good result even though it was the bottom of the pile of considered solutions.

I could then use a trick to extrude these projected shapes so they could be used for cutting ventilation and patterns into the surface of the orthotic. This would simply be done by booleaning the resulting forms. However both Grasshopper and Rhino would fail r crash when trying to boolean these shapes. I then tried exporting these shapes and using Meshmixer and Netfabb to do this (Netfabb has incredibly powerful boolean tools and will often manage operations that other software can’t) however both failed since the mesh that was being produced in Rhino’s export came out broken.

So I had to rethink what was possible to do for this project since I was now out of options and out of time. I decided to simplify the user customisation to just using curve and point attractors to make surface patterns.

Exercise 5.1 - Milling a Mesh Surface

Design in Rhino

8) Number sliders can be added to the variables Max Angle, Min Edge, and Max Edge to create different results on the surface. The other

9) The height of the extruded thing is a subtraction because subtraction makes one side flat. Otherwise, with an addition, it would be extruded in both directions. The number slider should be a floating point number rather than an integer.

10) The surface does not have to be lofted, we also created different surfaces with the command Sweep 2. However, there are some constraints: The surface must be able to be turned into a mesh and it cannot have any undercuts. A Euclidian object could be used to create a surface here. However, the surface should not lie flat in the xy-plane, but have height differences in z-direction for the project to make sense.

Manipulating ‘Virtual DNA’ // Human Intervention in Design Processes

“Like traditional drawing, digital production is a generative medium that comes with its own host of restraints and possibilities. Digital practices have the potential to narrow the gap between representation and building, affording a hypothetically seamless connection between design and making. As with any design process, however, there are invariably gaps among the modes of making. and, as with all tools of production, the very techniques that open these investigations have their own set of constraints and gear particular ways of working. Innovation is born out of this fissure and advances design.” - Lisa Iwamoto

While experimenting with the Grasshopper file, we found we were most interested in manipulating the maximum edge and the minimum edge of the meshed surface.

In our design process, we were inspired by the quote above and interested in testing and pushing the limitations of the meshed surface, technological constraints of the mill, and materiality. We wanted to exploit the gap both between and within design and fabrication processes, and recognize the possibilities and limitations embedded in each step. This impulse was catalysed by a desire to manipulate what DeLanda calls the “virtual DNA”, and experimenting with the “population” variable he describes: “adding points at which spontaneous mutations may occur” to the “sequence of operations”. The experiment reflects the ability of computation to mimic “mutant instructions to propagate and interact collectively over many generations”. This was done by altering what we established as “extensive quantities” (maximum edge and minimum edge).

We initially created surfaces by lofting from 3 or 4 closed curves, or by using the command Sweep 2, but most of these proved to be too complex for the fabrication process. Therefore, we created and meshed our final surface by lofting just 2 curves. We duplicated this surface, and then manipulated the maximum and minimum edge of both the volumes, producing visually different volumes that are both born out of the same profile curves and meshed surface. Our final product combines these two: One half of the volume is more complex, while the other half is a simpler rendition of the same initial surface.

complex side: min edge: 0.958 max edge: 8.989

simple side: min edge: 5.762 max edge: 8.882

Pilgrim at Tinker Creek by Annie Dillard

We don’t know what’s going on here. If these tremendous events are random combinations of matter run amok, the yield of millions of monkeys at millions of typewriters, then what is it in us, hammered out of those same typewriters, that they ignite? We don’t know. Our life is a faint tracing on the surface of mystery, like the idle, curved tunnels of leaf miners on the face of a leaf. We must somehow take a wider view, look at the whole landscape, really see it, and describe what’s going on here. Then we can at least wail the right question into the swaddling band of darkness, or, if it comes to that, choir the proper praise. (Heaven and Earth in Jest, p. 10)

***

I am an explorer, then, and I am also a stalker, or the instrument of the hunt itself. Certain Indians used to carve long grooves along the wooden shafts of their arrows. They called the grooves “lightning marks,” because they resembled the curved fissure lightning slices down the trunks of trees. The function of lightning marks is this: if the arrow fails to kill the game, blood from a deep wound will channel along the lightning mark, streak down the arrow shaft, and spatter to the ground, laying a trail dripped on broad-leaves, on stones, that the barefoot and trembling archer can follow into whatever deep or rare wilderness it leads. I am the arrow shaft, carved along my length by unexpected lights and gashes from the very sky, and this book is the straying trail of blood. (Heaven and Earth in Jest, p. 14)

***

When her doctor took her bandages off and led her into the garden, the girl who was no longer blind saw “the tree with the lights in it.” It was for this tree I searched through the peach orchards of summer, in the forests of fall and down winter and spring for years. Then one day I was walking along Tinker Creek thinking of nothing at all and I saw the tree with the lights in it. I saw the backyard cedar where the mourning doves roost charged and transfigured, each cell buzzing with flame. I stood on the grass with the lights in it, grass that was wholly fire, utterly focused and utterly dreamed. It was less like seeing than like being for the first time seen, knocked breathless by a powerful glance. The flood of fire abated, but I’m still spending the power. Gradually the lights went out in the cedar, the colors died, the cells unflamed and disappeared. I was still ringing. I had been my whole life a bell, and never knew it until at that moment I was lifted and struck. I have since only very rarely seen the tree with the lights in it. The vision comes and goes, mostly goes, but I live for it, for the moment when the mountains open and a new light roars in spate through the crack, and the mountains slam. (Seeing, p. 35)

***

This is the sort of stuff I read all winter. The books I read are like the stone men built by the Eskimos of the great desolate tundras west of Hudson’s Bay. They still build them today, according to Farley Mowat. An Eskimo traveling alone in flat barrens will heap round stones to the height of a man, travel till he can no longer see the beacon, and build another. So I travel mute among these books, these eyeless men and women that people the empty plain. I wake up thinking: What am I reading? What will I read next? I’m terrified that I’ll run out, that I will read through all I want to, and be forced to learn wildflowers at last, to keep awake. (Winter, p. 44)

***

When I was in elementary school, one of the teachers brought in a mantis egg case in a Mason jar. I watched the newly hatched mantises emerge and shed their skins; they were spidery and translucent, all over joints. They trailed from the egg case to the base of the Mason jar in a living bridge that looked like Arabic calligraphy, some baffling text from the Koran inscribed down the air by a fine hand. Over a period of several hours, during which time the teacher never summoned the nerve or the sense to release them, they ate each other until only two were left. Tiny legs were still kicking from the mouths of both. The two survivors grappled and sawed in the Mason jar; finally both died of injuries. I felt as though I myself should swallow the corpses, shutting my eyes and washing them down like jagged pills, so all that life wouldn’t be lost. (The Fixed, p. 56)

***

Nature is, above all, profligate. Don’t believe them when they tell you how economical and thrifty nature is, whose leaves return to the soil. Wouldn’t it be cheaper to leave them on the tree in the first place? This deciduous business alone is a radical scheme, the brainchild of a deranged manic-depressive with limitless capital. Extravagance! Nature will try anything once. This is what the sign of the insects says. No form is too gruesome, no behavior too grotesque. If you’re dealing with organic compounds, then let them combine. If it works, if it quickens, set it clacking in the grass; there’s always room for one more; you ain’t so handsome yourself. This is a spendthrift economy; though nothing is lost, all is spent. (The Fixed, p. 66)

***

This is it, I think, this is it, right now, the present, this empty gas station, here, this western wind, this tang of coffee on the tongue, and I am patting the puppy, I am watching the mountain. And the second I verbalize this awareness in my brain, I cease to see the mountain or feel the puppy. I am opaque, so much black asphalt. But at the same second, the second I know I’ve lost it, I also realize that the puppy is still squirming on his back under my hand. Nothing has changed for him. He draws his legs down to stretch the skin taut so he feels every fingertip’s stroke along his furred and arching side, his flank, his flung-back throat. I sip my coffee. I look at the mountain, which is still doing its tricks, as you look at a still-beautiful face belonging to a person who was once your lover in another country years ago: with fond nostalgia, and recognition, but no real feeling save a secret astonishment that you are now strangers. Thanks. For the memories. It is ironic that the one thing that all religions recognize as separating us from our creator—our very self-consciousness—is also the one thing that divides us from our fellow creatures. It was a bitter birthday present from evolution, cutting us off at both ends. I get in the car and drive home. (The Present, p. 80)

***

My mind branches and shoots like a tree. (The Present, p. 90)

***

If you analyze a molecule of chlorophyll itself, what you get is one hundred thirty-six atoms of hydrogen, carbon, oxygen, and nitrogen arranged in an exact and complex relationship around a central ring. At the ring’s center is a single atom of magnesium. Now: If you remove the atom of magnesium and in its exact place put an atom of iron, you get a molecule of hemoglobin. The iron atom combines with all the other atoms to make red blood. . . . (Intricacy, p. 127)

***

What if God has the same affectionate disregard for us that we have for barnacles? I don’t know if each barnacle larva is of itself unique and special, or if we the people are essentially as interchangeable as bricks. My brain is full of numbers; they swell and would split my skull like a shell. I examine the trapezoids of skin covering the back of my hands like blown dust motes moistened to clay. I have hatched, too, with millions of my kind, into a milky way that spreads from an unknown shore. I have seen the mantis’s abdomen dribbling out eggs in wet bubbles like tapioca pudding glued to a thorn. I have seen a film of a termite queen as big as my face, dead white and featureless, glistening with slime, throbbing and pulsing out rivers of globular eggs. Termite workers, who looked like tiny longshoremen unloading the Queen Mary, licked each egg as fast as it was extruded to prevent mold. The whole world is an incubator for incalculable numbers of eggs, each one coded minutely and ready to burst. (Fecundity, p. 169)

***

I have to look at the landscape of the blue-green world again. Just think: in all the clean beautiful reaches of the solar system, our planet alone is a blot; our planet alone has death. I have to acknowledge that the sea is a cup of death and the land is a stained altar stone. We the living are survivors huddled on flotsam, living on jetsam. We are escapees. We wake in terror, eat in hunger, sleep with a mouthful of blood. (Fecundity, p. 177)

***

Either this world, my mother, is a monster, or I myself am a freak. (Fecundity, p. 179)

***

Is this what it’s like, I thought then, and think now: a little blood here, a chomp there, and still we live, trampling the grass? Must everything whole be nibbled? Here was a new light on the intricate texture of things in the world, the actual plot of the present moment in time after the fall: the way we the living are nibbled and nibbling—not held aloft on a cloud in the air but bumbling pitted and scarred and broken through a frayed and beautiful land. (The Horns of the Altar, p. 230)

***

I am a frayed and nibbled survivor in a fallen world, and I am getting along. I am aging and eaten and have done my share of eating too. I am not washed and beautiful, in control of a shining world in which everything fits, but instead am wandering awed about on a splintered wreck I’ve come to care for, whose gnawed trees breathe a delicate air, whose bloodied and scarred creatures are my dearest companions, and whose beauty beats and shines not in its imperfections but overwhelmingly in spite of them, under the wind-rent clouds, upstream and down. Simone Weil says simply, “Let us love the country of here below. It is real; it offers resistance to love.” (The Horns of the Altar, p. 245)

***

I stood at the window, the bay window on which one summer a waxen-looking grasshopper had breathed puff puff, and thought, I won’t see this year again, not again so innocent; and longing wrapped round my throat like a scarf. (The Waters of Separation, p. 265)

The Best of Tutorial Tuesday: Create Mind-Blowing Designs With Parametric Modeling in Grasshopper

Over the next few weeks, we’ll be bringing you the best of our Tutorial Tuesday series, resurfacing the most popular and useful tips from past Tuesdays. Enjoy!

Why create just one design when you can create infinitely many? Instead of designing a ring in just one size, you could use parametric design to control the ring size or the surface pattern, effectively creating many designs within one. Parameters also enable you to create algorithmic, generative designs with amazing complexity.

A good entry point to parametric design is OpenSCAD; you can read more about it in our previous article Tutorial Tuesday 4: Using OpenSCAD to Design With Code. When you’re ready to step into more complex, even organic-looking parametric design, then it’s time to look at Grasshopper. Grasshopper is a plug-in that comes standard with the powerful 3D modeling software Rhino.

To give Grasshopper a try, you must first download a free trial of Rhino for Windows, or download the Work in Progress version of Rhino for Mac. Start up Rhino and type “grasshopper” into the Rhino command line; Grasshopper will open in a window that overlays your Rhino workspace. Creating designs in Grasshopper involves placing visual code elements and connecting them with input/output “wires.” The resulting forms can be modified with parametric sliders and then ultimately “baked” into Rhino when you find a desirable set of parameters.

It looks complicated, but it isn’t as hard as it seems; once you get the hang of it, it is easier than writing text-based code. Here’s what a typical Grasshopper design-in-progress might look like:

Grasshopper screenshot from Seth Moczydlowski

Getting Started with Grasshopper

For first steps, follow through the Grasshopper Getting Started videos by David Rutten. These videos will walk you through creating your first Grasshopper definition, working with sliders, and using the interface effectively.

Once you understand the basics of interacting with Grasshopper, move on to Mode Lab’s fantastic Grasshopper Primer. This primer is a printable online resource that can be used as the basis of a short but powerful first course on Grasshopper. This foundations course covers not only the basics but also more advanced key topics such as data trees, algorithms, and mesh geometry.

For more advanced tips, walthroughs, and examples, head back to the main Grasshopper site to check out their list of video tutorials:

And finally, you can order a printed reference for Grasshopper: Dave Bachman‘s excellent new book Grasshopper: Visual Scripting for Rhinoceros 3D. The first half of this book is a thorough introduction to Grasshopper, including very detailed breakdowns of Grasshopper scripts for key example designs. The second half is an extensive Component Reference, which is handy to flip through to get new ideas or a birds-eye view of available options.

A simple Grasshopper design

So what can you design with Grasshopper? Anything from simple forms to complex algorithmic designs. Let’s start with a very simple example, our own Witness Bracelet from the geekhaus shop:

This bracelet was designed by sketching out the Witness path shape on a flat plane, extruding around that sketch with a tube, then wrapping the resulting form around an elliptical cylinder whose dimensions are determined by parameters that represent wrist width and height. The Grasshopper code for those actions is the mysterious mess of wiring shown below:

Of course, we could have created this simple bracelet in a much simpler, nonparametric way, but using Grasshopper enables us to move sliders to control wrist size measurements, path definition, and other features. This means that the Grasshopper code can create millions of variations on our design, and we decided to print one of them.

Parametric Power

Designers who leverage the power of parametric design don’t create just one model at a time, they create whole families of models with adjustable parameters. For example, consider the stunning Clothoid.A Lamp by Alienology, one beautiful form chosen from a huge array of possible designs created with parametric lofted splines:

Using the same Grasshopper code and modifying certain parameters, Alienology also created this very different Clothoid.B Lamp:

As another example, consider the work done by Responsive Design Studio in Germany. Using Grasshopper, they created a parametric ring design that can be customized to finger size, width, pattern, and other preferences.

Have you been creating parametric designs with Grasshopper or other modeling software? Tell us about it in the comments for a chance to be featured in future Tutorial Tuesday posts.

Or, if you’ve got questions about Grasshopper, leave a comment so that someone in the Shapeways community can help you get started.

15 Precious Tips To Help You Get Better At metal fabrication.

youtube

I began with a step-down of 3/8″ and also a step-over of 1/4″. If the block was taken care of to the table, that’s really affordable! Allow’s see exactly how it went shall we? Clamped in the head stock chuck it’s all set to go. It began great but throughout a helix lead-in the higher pull of the endmill was too much for the rotating electric motor to hold – the block turned and the little bit gouged it. What permitted the cutting to be precise and mistake totally free? Careful Toolpath Programming: As gone over over this is important. Refining the toolpath as you see it reduced is a basic component of CNC craftsmanship. I transformed the shows a minimum of 5 times as I viewed a lot more and also extra parts being reduced. As an example what operated in forgiving Poplar really did not work also it splintery Cherry. I needed to change the cut to eliminate it. Sharp Tools: There is no alternative for sharp router little bits. Heavy training entails lowering your body’s middle of gravity. Twisting in the legs increases stability and uses heart that is reduced, a well balanced. Training is just begun after the neck as well as back muscle mass are comfortable. Upper body muscles shouldn’t endure the weight of the thing being moved; they need to only be made use of to set up the point near to the body. Whenever feasible, sheetmetal workers must intend and position their workstations as well as products so that heavy things might be lifted from midsection high in a standing setting.

Note: These values are all in millimeters.

You could see that the A axis represents vertical in the layout. The top robot hanging from the component is called Titey. It has a different X, Y and Z counter turnings and worths. Make use of the seeings below when your definition ought to operate on Titey. Note: These values are done in millimeters. special info The function of KUKA|prc is to generates the code which operates on the robotic controller. This code is composed in the Kuka Robot Language (KRL). You should tell KUKA|prc what directory site as well as documents name to utilize for its code output. When you’ve done this, as you make changes in the UI, the outcome will be re-written as required to keep the code up to date with the Grasshopper definition setups. A few of the examples of very flexible steels are gold, copper, aluminium and also silver. These steels could be framed into different forms without fracturing. However there are few individuals that will claim that innovation has taken the skill from sheet metal construction however the opposite is true. When applying modern technology to the procedure, different kinds of skill set are required. Actually, innovation goes to the forefront of today’s sheet metal construction industry – Going Here – .

Silicon carbide media might be utilized, especially for the lasts of finishing. Avoid making use of hard objects such as blade blades and also specific abrasive/souring representatives as it is possible to introduce surface scuffs and scratches. Damaging is particularly recognizable on sink drainer locations. These are normally surface and also could be eliminated with proprietary stainless-steel cleansers or, conversely, with an automobile paint conservator, such as ‘T-cut’. If wire brushes are made use of, these should be made of a similar or far better quality of stainless steel.Steel fascia

However, the largest contribution it has is on utility systems. You could see that they are utilizing it totally on building and also the production of systems that are required for the structure to be functional. Online stores are currently available for others. Several establishments are currently discovering the importance of being online considering that it additionally enables them to reach a vast array of consumers. Gold finding in superficial waters is simpler compared to searching for gold on a beach due to the fact that you run a better possibility of striking after the

bounty easily. Lots of visitors shed jewelry and also coins while playing in shallow waters making them rewarding places. If coastline hunting is exactly what you plan to do, make certain that you go in the evening when the sands have actually run out and also the groups dispersed making it very easy to find the prizes. There are many online websites that deal in gold spotting makers and miners of all feasible categories. These websites are best resources where you could gather valuable ideas on the equipment, their upkeep as well as operation amongst others. This sapwood is where water and liquified nutrients(minerals)are moved in between the origins and also the fallen leaves of the tree. In the outer growth rings of a tree(those near to the bark-away from the center) sap flows via the “straws”of the timber. Commonly the sapwood is a various color compared to the heartwood. In most species, the sapwood is lighter than the heartwood. An exemption to the sapwood being lighter is Sycamore. Its sapwood is darker compared to the heartwood. Lumber is commonly priced by an amount called a board foot. This deburring cpu is extremely reduced and extremely hostile maintenance. This means much less time invested on private components, as well as even more time is permitted the consistent circulation of work. Parts are fed right into the front of the device, where any type of slag is ground off the surface of the sheet steel or machined part. After that, it has revolving strips of sandpaper smooth off any type of sharp edges, as well as lastly, a turning drum of fining sand sheet includes a smooth grain to the surface. With over 60 years of experience in custom manufacture we have actually developed a wide array of components for building, commercial and industrial applications. We have actually supplied numerous steel fabrication bundles for building and also relevant elements consisting of doors, thresholds as well as hand rails. Our commercial clients call us for conveyor sections, diverter arms, footways, mezzanines, systems as well as more. Our architectural expertise consists of making extruded light weight aluminum and architectural supports for drape wall surfaces, store fronts, sun shades, wall braces and also comparable components. Costs largely depend upon come with bed mattress. From the traditional box springtime cushion, bedroom furnishings manufacturers are currently utilizing memory foam cushion, air mattresses and pillow top bed mattress in an effort to add more convenience and a softer rest. The firmness of steel beds is vital to ones tastes and also choices. Because metal beds are typically box springtime type, they are softer contrasted to system beds. If your existing bed is rather tough and company, after that box springtime kind steel beds might be a great solution. A solid steel metal bed framework supplies a lasting firm foundation for the bed collection.
