I’m trying to project a set of shapes onto an irregularly shaped roof, so that the shapes are evenly spaced on the surface. Is there a simple way to do this in Grasshopper?
After this is finished, is it possible to subtract a portion of the grid using a different shape? (see second sketch below)
Thanks for the help!
Given the fact that Rhino is a surface modeller for a perforated solid I would suggest (can we forget the “even” distribution part?, he he):
Separate pieces meaning that: use a surface and make the rest of the “solid” faces as indicated in the attached.
Morph your “profiles” to the flat part - the base so to speak (for speed).
Extrude the mapped profiles (straight). Avoid projecting and then doing the solids (very slow).
Do the boolean difference as indicated (Note: that’s very slow).

Or alternatively Morph the profiles directly to the curvy surface (Note: that’s very slow and pointless if the perforated solid is your goal)
Thank you so much for the help! This is definitely a good way to get started. I think I’m looking for something a bit more nuanced though, and probably didn’t phrase my original question very well. I’m going to re-post a new topic, rephrasing my question. Would love to get your feedback there! Thank you again
