Random Numbers to Family Parameters


There are simple ways of looking at random numbers, and then there are awesome ways at looking at random numbers. We shall explore both (and write them to family parameters in Revit).

Get Mass Floor Data


Revit Massing studies + Dynamo = Love.


There is an interesting quirk in extracting data from Revit Mass Floors with Dynamo (probably any Revit API tool).  Levels that are assigned to masses that don't hit the floor come up as blank data (not zero, not null), so there is a little cleaning up you need to do.

Datasets can be downloaded from here.

Happy Halloween VI



It’s time to announce the winners for the 6th Annual Parametric Pumpkin Carving Contest.  Usually, we have the Baddest, the Goodest, and the Mostest Parametric.  There may be a need to make some adjustments this year . . . I think Andy Milburn broke the system.  Imagine that instead of a Parametric Pumpkin Carving we were having a Biggest Pumpkin competition, and we had a nice little scale to weigh each pumpkin.  Imagine someone showed up with a 5000 lbs pumpkin and dropped it on the scale . . . all the spring go shooting out in all directions as the device crumbles to dust.  

But I'm getting ahead of myself. 

The Baddest
by Neil86
“Bad” in this case is regarded as high praise for an uncanny scariness, a serious and terrifying aspect.  

This year's winner for Baddest comes in with Neil86's punk rock classic.  It ain't slick, it ain't pretty, but it sure looks mean and I wouldn't want it in my room after the lights went out.  Like the Ramones or Dead Boys, this nasty little beast is the equivalent of 3 chord manifestos like Sonic Reducer. The 3d print pushes the medium into elegantly broken and drippy spasms that at once seem on the point of collapse, while expertly evoking pumpkin slime.
Well done Neil86.  Please don't hurt me.

The Goodest


by Scott Crichton, Architectus, Brisbane Australia
The pumpkin that gets to the wholesome essence of both Jack O' Lanterns and the design platform on which it was built.  Free of workarounds and hacks, this winner is a model of both creativity and good citizenship.

Scott must have fried his poor hard drive, with this magnificent collection of 22752 Lego block Revit Families.

Wait . . . whut?

Ya, 4212 Big blocks and 18540 Actual size.  In his own words:
"The concept was rather simple, create a Lego family that can be applied to Mass forms to give the effect that it is made out of Lego. From this simple concept began a very long journey of experimentation and refinement.

First things first, getting the Lego block modelled properly….. so the family now has some formulas that control the buttons on the top and the circular modelling underneath all controlled by the length of the block. I made the Lego size correspond with a typical concrete block module size (standard in Australia), 200mm wide 200mm high and 400mm long (with the length being flexible). An added little bonus is that if we want an actual real life Lego block size I put in a scale factor parameter that would scale everything down to an actual Lego block size, 16mm wide 9.6mm high and 24mm long. The last step was probably a bit of overkill but I wanted to push the family. (I thought I would even put the word Lego on the top of the buttons but that would be going too far......it was already going to take ages to populate the mass!!!)

The next step was the colours......this I found to be much more of a challenge....I have a randomiser add-in so I though great, use that.....but it only works in a project file and it will not work on the individual blocks in the Curtain panel....We also use BIMLink, I created some individual materials for the Lego colours and then I created a schedule, exported it out and using excel to randomise the materials imported it back in to my model.....same result, you can't individually control the materials of a curtain pattern family. I then had a look at creating a filter to change the colours of the Lego blocks based on their length, this worked great but I thought it was sort of the easy way out and it created bands of colours in my model, not really the random result I was after. So back to the drawing board....then I decided that I needed to look at using a different family type. So I hosted the Lego block into a 2 point adaptive family and then loaded it into the mass on the nodes of the divided surface. Then using the repeat tool, I created my logo blocks. Worked great (almost), unfortunately I had the same problem with randomising the colours as I did before. This is when I thought about a reactive component. So placing a control point in the adaptive family I created a sin wave formula and used family types to create the randomness. This was the answer and when it was loaded into the mass family with a control point I got my random blocks, plus you can change the randomness by moving the control point. Hooray!!!

Creating the pumpkin form was relatively easy in comparison, creating a profile from a couple of reference circles and hosted points (using the measurement type and specifying an angle), some splines for the segments, overall radius parameter controls it all. This then gets loaded into my pumpkin mass hosted to a few reference planes and then created the form and dragged the top reference plane down to create the shape. Same process for the little stalk at the top. Parametric Pumpkin Done!

The pumpkin was ready to be Lego'ed......

The surfaces were divided up and nodes activated, the U and V grids were adjusted to allow the blocks to stack nicely for the heights, and an ok length for the grids set. Then I started placing the Lego into the individual segments. Each segment took Revit about 15 minutes to repeat the component pattern, a bit of a side effect from having such a detailed Lego family. To add a little bit of a bonus I created the stalk of the pumpkin using my actual real life Lego blocks, 9.6mm high!!! In total there are a total of 22752 Lego blocks in the pumpkin (4212 Big blocks and 18540 Actual size), probably a good reason why it took hours to transform it into Lego. The mass family file size is now over 100Mb!!!"

We would offer the file for download . . . but it's 100mb!

Mostest Parametric

The pumpkin that is shaped by rules and variables, that is definite yet infinitely flexible.  It not only defines a particular look and feel, but conveys the possibility of endless variation.

It's difficult for me to talk about Andy's latest work.  If you've seen the movie Groundhogs Day, think of the final speech made by Bill Murray, where he takes the occasion of a throw-away event (the announcement of Punxsutawney Phil's prediction of how many more days of Winter there will be), and uses it as the poetic vehicle to encapsulate the depth of experience of an immortal life.  This is Andy's pumpkin.

If you have not seen Groundhogs Day, just know that Andy Milburn's work is moving and absurd and virtuoso and inspirational and goofy.  For those that already know him, you have probably been following his activities on his blog Grevity, where he has been building and exploring desert ecosystems, human settlement patterns, trends in the evolution in world art, proportion, monumentality . . . and more.
Then a couple days ago I look in the mail and I see Andy's full submission . . . a thesis really.  A 90+ page competition entry on "The Desert Pumpkin.  The ongoing effort to improve the way that information is used in the construction industry.  Digital tools to enable effective decision making". Beginning with precedent studies of the monumental architectural proposals of Ledou, and Boulee, Andy searches for connections between the intimacy of ancient domesticity that emerged out of the Fertile Crescent and the overwhelming vastness of the desert landscape.  Along the way he finds a formal language to connect the small and tangible with the limitless. 

So what does all this have to do with parametric design and BIM?  

"BIM is habitually referred to as a technology, a documentation tool, a means for increasing productivity and revenue flow. What then of art ? Why do I insist on probing the intersection between BIM and the artist inside each of us ?
In the late nineteenth century as the classic phase of the industrial revolution reached its peak, the world of fine art was thrown into turmoil. Photography had undermined many of the artist’s traditional areas of expertise and authority. The impressionists looked beyond photo-realism to explore fleeting effects of light and mood. Some sought to capture emotions directly, others to simplify and abstract in search of pure form.
Cubism was a short-live movement based on the concept of capturing multiple viewpoints in a single image. We do not experience the world from a static position.
Our memories are not discreet entities, but blurred and subtle composites.
Art is many things: a search for truth; an exploration of beauty, horror, simplicity, ennui; an expression of status; a challenge to authority.
Architecture is more than just a business. Our lives are more than a series of workflows. We crave meaning and purpose. Enter the artist within our soul.
It is not yet clear what “BIM art” would be. Photography was not considered art when first developed. It took time to learn how this new medium could be used to explore meaning, to balance form and content as all art forms must. As an engraver I could be a technician, just doing my job, efficient but sterile. Or I could seek to combine skill and meaning into a seamless whole. I could use my mastery of technique to express ideas, try to capture the essence of engraving and convey emotions. An artist like Escher was able to weld form and content in the most magnificent manner.
The inscription on a Ledoux drawing reads “Le Doux, Architecte du Roi” and “Grave par Van Maelle” Here we have a partnership between Architect and Engraver. The combination of technique and vision may not be as seamless as an Escher, but it is evocative none the less. In some ways the mechanical methods of the professional print-maker are better suited to the utopian messages purveyed by Boullee and Ledoux."

We at Buildz can only stand back and gape at what Andy has given us.  Please please please download his competition entry and read it.  And don't forget to visit his blog at http://grevity.blogspot.com/

Thanks to everyone who submitted entries. As always, we at Buildz are humbled by the efforts of our readers.  All our finalists will receive a choice piece of Buildz schwag, and our heartfelt thanks for participating.

Time is running out!

From Vintage Ephemera

Pumpkin deadline is looming, Oct 28 is nigh!

We've had a pretty good track record over the 1/2 decade of pumpkins . . . the form never fails to yield up new variations on the theme.

Getting a little nostagic and looking back at Year One, with finalists using Revit, Rhino/Grasshopper, and Inventor, submitted by the Greats: David Light, William Lopez Campo, and Rob Cohee.
http://buildz.blogspot.com/2009/10/happy-halloween.html
Interesting that, while at the time only Rob was working for Autodesk, now William and David are too . . .
Check out the whole catalog, look for MEP, video games, early Dynamo prototypes, and other inventive oddities.

Galactic Pumpkraft

3 best things I saw this weekend:

  • Marvel Comics Dazzler issue #11, featuring this image of Galactus, godlike cosmic traveler, devourer of planets:

Loungin' like a boss in his fine post modern laz-e-boy.  A lesson to all you would be world dominators to occasionally kick back and take it easy.

  • 11 year old Green-Octopus-Spider-man's Minecraft stuff made real via jMc2Obj to Meshmixer to Repetier to Printrbot.
  • Revit Structural Framing and Floor pumpkin sketches via Dynamo (git yer red-hot pumpkin maker component on the Package Manager now)
15 days to Pumpkin!  What better way to celebrate Invasion Day than with digital pumpkin carving?

6th Annual Parametric Pumpkin Carving


(Four months later . . .)
Sometimes the bottom falls out . . . the buildz-mobile catches a flat, the water heater explodes, some joker hides a bunch of fresh bananas in your cape just before you unleash the flying monkeys on disloyal minions . . . what have you.

Well, that isn't what happened.  We at Buildz International Inc, LLC, have just been real damn busy.  And neglectful.  Sorry about that, and thank you for your concerned letters. (BTW, "riddance" has 2 d's, you illiterate cretin).  We pledge to do better starting today.

And so, to kickstart the old beast back into production, we happily announce the 6th Annual Parametric Pumpkin Carving! Lubricate your fuse deposition modelers, fuse your model lubricants, and start making hierarchically engraved vegetables!

Prizes, as always, will be awarded for The Goodest, The Baddest, and The Mostest Parametric.

Remember that we at Buildz Open Sores Software and Vegetable Perforations LLP are platform agnostic. Submit entries from whatever tools you are comfortable with: Flood, Lego, LittleBits, abacus, Abaqus, all are welcome. Our factory judges are not judgy (well, we are, but we do it behind your back).

Along with receiving bragging rights, the winners will have their work showcased on these pages to the tens of readers of Buildz, and receive a valuable piece of Buildz schwag. Entries must be received by 12 noon EST Oct 28. Winners will be announced at midnight on Halloween.

So pour yourself a Dynamo (actually, don't), boot up your AKAT 1, and make a web-gl viewable, json based, gluten-free, smart-watch compatible Jack O'Lantern. Post entries to zachkron@gmail.com, at least a screenshot, but feel free to send models, journals, parameters, videos, scripts, whatever, modeled in whatever you like. If you have some huge-ass file, please send a link or let us know and we can work out some kind of upload.

A parting allegory/quiz:
A freshly poured cold beer is put on the counter just before the phone rings. When the pourer comes back and it's warm, (BTW, this is known as Alchohol Neglect) the pourer must decide whether to drink this flat, warm beer or pour it out and start a new one.
What is the proper course of action?

I love me a Parametric Bridge


I have a crap-ton of other stuff to do, and it's sunny outside, but I know that you, dear reader, really really need  a slightly impractical bridge to get you into the weekend.  So here is my triumphant (and somewhat muttering) return to screencasting: setting out geometry for a fancy pedestrian bridge, from scratch, in Dynamo.


Download the .dyn file from here.

I will follow this up with clothing this in Revit structural framing, and flexing.
