ep 1) build the facade skeleton with the outlines intersected from Voronoi cells and the skin of skyscraper. then use a some borrowed GH-sets to loft those outlines.
step 2) use some other borrowed GH-sets to loft the whole 3D Voronoi Skeleton. Then bake them. and then use "mesh boolean" in Rhino, to get the inner 3D Skeleton for the Skyscraper.
step 3) combine them, it's not perfect, but not too bad.
This is the result.
Problem: When I try to make the Point cloud more denser, the "mesh boolean" allways failed out. Because those Skeleton-meshs are too komplicated to split.
So is it possible to get the 3D Voronoi Skeleton just in once? To combine the inner 3D Voronoi and the facade-intersection?

ple and/or easy.
I use GH/Rhino (really GH almost exclusively) for design. I find the parametric capabilities of GH simply spectacular. The Autocad apps are all quite good (and free) so I would have no problem recommending any of them. Meshmixer is a common starter for people new to 3D printing; it is targeted at more "free form"/artistic designs that is Tinkercad, which is more oriented for geometric/engineering/architectural designs. Sketchup is also a good place to start with 3D design; it used to be owned by Google but is now owned by a 3rd party company.
For slicers I've tried them all and have settled on Craftware. It's free and available at https://www.craftunique.com/craftware. For backup to that (it is still a beta product) I use Simplify3D (very seldom) but it costs $150.
If anyone cares I have uploaded an updated version of the Stepwell GH file; I tweaked it a bit to make it a little simpler and to make the base thicker so it would be more robust when printed. The dimensions of the part are large so it has to be scaled down to fit a particular printer. This is easily done with any slicer. The STL file from Rhino still has to be fixed; as exported it would print with no bottom - and I haven't figured out why that happens.…

er many trials and errors), HelioCell is a prototype of a dynamic space which adapts itself to capture the most solar energy it can. This prototype was designed and studied in Rhinoceros and Grasshopper 3D with the help of gHowl, Geco, Kangaroo, and Firefly.
The team consisted of IaaC Faculty and Alumni. The 15 participants who are now part of the IaaC Family represented 12 different countries and were a truly amazing group.…
e the same (a 3d point is 3 floating point numbers), is to measure if their difference is smaller than a tolerance value.
For example, check if the distance between the two points is smaller than 0.01. If it is, assume that they are the same point.…

Then the challenge is taking the cells that you get from it and making them all smooth and sexy. Which is something I would probably look into weaverbird or exoskeleton for.…

ts is very large on the end user. My end goal is to have the script specify the connectors for any pipe being used. This is an academic project, but I am experimenting with MakerBot technology to 3D print the connector. The trick is to work within the constraints of using a MakerBot versus a commercial 3D printer. The advantages are huge though, open source 3D printing using basic ABS that costs pennies versus proprietary tech that costs 20 dollars a connector.
Mathematically, it appears there are only 3 different kinds of connectors, because there are only three kinds of pipe lengths. The Pentagonal which connects to only the short segments, a hexagonal, which connects only to the longest segments and common hexagonal which connects to all three segments and it is the most numerous connector. Ultimately, these connectors and segments should be color coded for simple assembly. My goal is that a group of kindergarten kids could figure it out without help.…

dy, that's perhaps why there there is such a discrepancy of lines in the ears as opposed to the body.Alternative proposal: 1. Start with a 3d populate bounding box with lines between two points, This bounding box must encase the Target geometry. ie the Bunny.2. Input the Bunny Mesh3. Trim the 3d populated bounding box with lines. up to the boundary of the Bunny Mesh. What remains are the lines contained within the Bunny Mesh.4. Now let the Cocoon script do its thing.Does this approach make sense? But more importantly is it doable in GH? (I have a Bounding Box)…
fore created by the intersection of the planes. At the boundaries- where there aren't any more points, the voronoi cuts off like a cube since the cell at the edges is infinitely big.
The reason why it looks like a cube in your model is because you only have 3 points which isn't enough to define the cell you're after (4 is probably the minimum).
TIP: you can use Populate 3d to generate random points in 3d Cartesian space OR populate geometry to randomly generate points on a surface. see attached
