I am an architecture student in their final year. My building is partualy inspired by rocks and other natrual form so i have made a super organic shape that i now need to split into multiple smaller panels to create a paneling system for the exterior. I have tried a few methods to do this and non seem to work. To create the lines that i need i drew across the surface of the object and then made pipes so that when the objects splits there is a gap between the two pannels. There are two types of pipes that i have used, virtical ones in pink are thicker to exentuate the virtical aspect of the building. I have used grasshopper to try and help with the work flow but it causes strange errors. I have also tried using the panel plug in but that didnt seem to work as the vertexs are snapped to the edge of the subd pannels which is not where i want them.I will put loads of images to reference what i am talking about. if anyone can help me that would be amazing as without the panels the building looks strange and unrealistic. Please let me know if you have any questions that might help to solve this problem. I am in my final year now and feeling very stress haha
hi, i am new to rhino so dont know what you mean by code. the object is modeled by hand using a subd workflow so i dont have any grasshopper codes to show apart form the one i have uploaded. let me know how to get the code and i will share it with you asap
Surface Split.gh (22.9 KB)
this is the only grasshopper i have used to make this project, this was used to create the pipes from the curves and then to cut the subdsurface after being converted to brep
so you already know, that your grasshopper file does not do anything wthout your 3dm file. dont you?!
you still havent uploaded geometry
(could be internalised in grasshopper or seperate file)
Your file link no longer works but from the post I think you want to rationalize an organic form into panels. There are many workflows to consider and lots of tools that may be useful to you. See PanelingTools for Rhino and Grasshopper | Food4Rhino for instance.
However, I think the ultimate issue here is that you didn’t use ToNURBS on your SubD prior to using Split. This will pack as many quad faces in the SubD into single surfaces in the resulting NURBS polysrf. With far fewer edges in the Polysrf, you will be less likely to get bad trim results which result in bad render meshes as you showed initially here.
