I have been trying to make a ContactMesh for a forward dynamics simulation, but it seems as though the mesh is not being formed properly as it doesn't interact with the half space contact geometry like the contact sphere does. I have been exporting .obj files from solidworks for the contact geometry, but I am starting to think this might be wrong. Can anyone explain to me how I would go about creating a file compatible with the ContactMesh function from a solid part in solidworks?

Thank you!
