i am currently working on a task, extracting geometry from IFC file and point cloud and building solid meshes and compare them getting the differences.
but as I use generated point cloud solid meshes and IFC solid meshes from IFCwall IFCdoor IFCwindows and IFC Column. but the geometry is always invalid when i put them in to CSG builder.
how can i compare difference of two big geometry and what kind of geometry accept CSG builder ?
