I try to create a 3D rigid body in Abaqus. However, there is always an error when I assemble it. Abaqus says that I have to convert the 3D rigid solid body to rigid shells. I don't know why this constraint applies. When I change the rigid solid to rigid rigid shells, however, I would not be able to use the cut geometry function.

So, basically, is there a way that I can assemble a rigid body and also make it cuttable?

Thanks,
