generative modeling for Rhino
This is not a simple script, not intend for general purpose.
The script still relies on solid Boolean operations, thus limited to what Rhino 'can Boolean'.
I'll add more description about the script later when I have more time.
I attached a form testing file, which you can play with some forms that I've sketched.
This is my first post, suggestions and comments appreciated.
Inspired by David Fano's Parametric Truss script.
waffle_20101228.ghx, 1.6 MB is the latest script (hope it works on GH0.8)
Sorry for the incomplete tutorial,
The unit used is the rhino unit, so what ever unit your model is in, the GH takes that unit. The sections are weird because you have set the spacing too wide, and the material thickness may be too thick, try to have around 15 to 20 slices, and have a reasonable thickness (1/3 to 1/10 slice spacing)
Thank you Victor. It has been working nicely. Question, what would cause the section to fail in one plane only? Certain x and y spacing yields areas where the section does not calculate.
I wrote this script long time ago, I forgot why :P
I recalled some fact is that, when the planes are cut exactly at some parallel surface. Or simply if Rhino Boolean calculation give up, it will fail.
that is why sometimes changing the location of the geometry, or plane spacing or something else slightly (very slightly: say less than 0.001 unit) might get rid of the problem.
Another thing is that your geometry is better neatly build, water tight is a must. No overlapping or self intersecting surface, etc.
Thank you Victor for your definition. Working nicely.
Thanks for sharing this.
It's going to open up many opportunities for 3d studies.
Relativley new to Grasshopper but can understand alot of your fabulous script.
I've having trouble using it.
When I set my Brep the section turns red and then the list of points that determind the X and Y spacings disappear???
Any tips would be much appreciated.
I'm not sure, that sound like a Rhino bug. The section planes should appear if preview is turned on. Even with any other error that happen.
Make sure you are using GH v.0.8.0004
Try draw a box in Rhino and reference it to test. Test the script with something very simple at first might resolve the problem.
I had the same problem, you have to get the other definition victor posted a little later for grasshopper 0.8 and get your sections planes/material thickness right.
Thanks a bunch victor your a life saver. Ive been working with t-splines, making some organic floorplanes/facades. For the construction i was thinking to do a waffle shaped construction, but i wasnt able to adjust a waffle script from digitial toolbox for multiple/complex Breps. So im happy ive found yours because: T-splines -> water tight polysurface, and thats exactly what your definition wants to be feeded :)
Glad that you find it helpful,
I've updated the post, so that waffle_20101228.ghx is in the attachment list.
I have GH version 8.0007 and I cant get it to work so should I download a previous version of GH?
P.S. this script look AMAZING so increadibly useful! Just got to find a way to use it haha
