I downloaded an stl file of a warthog from halo to base my design off of. It came as a mesh, which I can't work with on inventor (or fusion apparently). I need to be able to work with it so that I can see each face and how it goes together. Is there either a way to convert something from a mesh to a body or a way to work with the mesh (or a stl file)? If not, is there anyone able to help me make one from scratch?
