I was working on a grasshopper script that used perpendicular frames along a curve, on the outside of a building > BREP > boolean difference to create shadow lines / panel lines to polysurfaces, for 3D printing architecture models.
It works okay, but I often encounter boolean difference failures. With some manual work I can make it work, but I was wondering if there were more reliable, quick methods to use. I was using a square profile to form the BREP to be subtracted from the polysurface.
However, I realised that a V shape would be more ideal - But I was having issues again, with boolean subtraction. It’s probably because it was one continuous curve, with 90 deg turns along the floorplate of the building. Before I could change the GH script to process all the individual straight curves, I discovered a much better solution - the Shuttinglines feature!
This is exactly the function I want. Except about 1 in 8 shutting lines “fails to render” - I have the exact same issues as seen in this thread below:
My question is; is there a specific render mesh setting you need to use for this to work reliably?
I am happy to provide my file in question - but the polysurface is solid, has no issues or manifold issues, naked edges etc. But it still fails.
Is there a better method? Because this is for 3D printing I need watertight meshes. this is slowing down my workflow and I need something reliable to use for all projects. Has anyone worked out a good workflow, please? Thanks!
