SpaceClaim (before it was even ANSYS) has been our tool of choice for all mechanical design. It is a very capable 3D CAD system. My company has released hundreds of sheet metal, injection molded, and machined parts/products designed and implemented all the way through concept to release in SpaceClaim. The direct and modeling tools are incredibly powerful. The fabulously versatile "Pull" tool has no equal in any other CAD package I have used. I have used Fusion360 pretty extensively. SpaceClaim requires far fewer "clicks" and menu traverses to get the same job done and generally is 20-50% faster to model any given part.
