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 ?
+19Hi @fdh12316,
The IFC data is read as a solid aggregated to a number of Null instances containing the Property Set information. You may need to use a GeometryPartExtractor to extract the solid geometry from the aggregate before sending to the CSGBuilder. I would also recommend using a Clipper instead of the CSGBuilder, since it has been recently updated for performance, and may give faster results.
