algorithmic modeling for Rhino
I guess I'd like a grasshopper approach to the "curveboolean" command in rhino...
Have you tried Region Difference under Intersection-> Shape?
Hi Ethan,
Thanks for the response, I am aware of those intersection components. I guess my real problem here was coming up with a clever way to solve multiple intersections at once... Any ideas?
Here's a start...but it's hard to determine exactly how to do this with grasshopper if there's no clear hierarchy to the group of squares. I think it might be better to just use the curve boolean command in Rhino.
The quick definition I made separates a list of rectangles into two halves--small and large, but doesn't address the issue of establishing a more local hierarchy. In other words, you might have a group of rectangles which falls completely into the list of smaller rectangles (since it samples the entire population), but none of them would be trimmed with each other.
Hi Christian,
Thank you as well for the quick response. Like I mentioned to Ethan and you mentioned in your response, the real problem here is creating that hierarchy, and I'm beginning to think this is a much more loaded question than I had hoped for...
Let me know if you have any other ideas and thanks again for the work!
in my opinion, it should be simple
by sorting according to area, you extrude according to new order
then you use rhino command make 2d
done below
Clever! I guess you're assuming the extruded heights vary like the the area.
exactly sort surfaces according to area, then extrude according to index value
when use make2D command, make sure not to draw hidden lines(settiings)
hmmm that is a pretty clever approach Mohamed. I was trying to stay completely in grasshopper, so maybe there's a different way to get this new line work other than using Rhino's Make2d... I'm going to give this a try and let you know what I come up with.
Thanks again for the help!
You might not need Make2d, after the extrusion you can:
_solid union the boxes
_extract from the joined brep only the faces with a z normal (assuming you are drawing in XY plane)
_extract the edges of the faces and project back to XY
Should work right?
