I am working on a project where I need to determine the volume between two 3D scanned objects. Because 3D scan data is produced as a point cloud, I have used Meshlab to create a mesh and FreeCad to create a solid part. The solid part can then be imported into SolidWorks and the Tool -> Mass Properties option can determine the volume of that part. So far these steps work for finding the volume of one 3D scan data object. Now I am wanting to apply this same process for two 3D scanned objects, but delete the common material between them to get the volume of a specific region.

Object 1: Simple cube (see attached image)

Object 2: Simple cube + smaller cube on top (see attached image)

I have attached a screenshot of the two objects in SolidWorks (see attached 'blocks' image) and now want to delete the highlighted blue region to get the volume of the smaller block on top. Is there a way to do this in SolidWorks?
