At the beginning i had open meshes (on the layer: “original open mesh objects”)
I wanted to close all the open meshes using grasshopper but i did not succeed.
So after half a year of trying, i put it to Microsoft 3d Builder which closed all the open meshes but also combined them to larger meshes.
The result is on the layer: “objects from 3d builder to be split”
Now i want to split these buildings into smaller parts again for my urban analysis.
Therefore i generated Splitting objects.
I put these splitting objects on the layer: “splitting objects”
When i try to do a Mesh split it always fails in parts.
Best thing would be to just close the “original open mesh objects” without combining them like 3d builder does.
I want to do some volume analysis therefor they need to be closed
I notice the polysurfaces have thickness. Do you want to remove a slot the width of the polysurface from the mesh, or do you want to use the center line of the polysurface to cut the mesh?
I am still looking into this. I have been busy finishing up work for another forum member struggling with reading point clouds. I now have this squared and will begin looking at your example again.
