What you can do is to get the volume of the mesh before and after the cutout, and subtract the two.<BR /> <BR /> Best, Akos Tue, 20 Nov 2018 11:21:20 GMT https://community.graphisoft.com/t5/Archicad-C-API/How-to-get-solid-operation-substraction-volumn/m-p/256065#M3401 Akos Somorjai 2018-11-20T11:21:20Z https://community.graphisoft.com/t5/Archicad-C-API/How-to-get-solid-operation-substraction-volumn/m-p/256066#M3402 Hi Akos,<BR /> Yes, I created a new mesh with the same mesh and deleted it after getting the original volume.
