3D volume CAD software for sheet metal
CATALCAD

SMO does it all for you: it reads imported 3D models and automatically transforms them as "sheet metal" models in its own data base. The user then has a whole range of highly powerful tools to unfold the model in whatever way he wants.

The user can, for example, cut up the original model into several parts. Once obtained, these parts remain easily accessible for all types of modifications.

With SMO it is possible to create entities and thus add the holes, faces (in this case SMO automatically creates the folds), bevelled edges and grooves required for manufacturing. SMO thus completes and adds the finishing touches to the initial design.
SMO can also be used to make interactive dimensional modifications (Free D.O.M.) to all geometric parts.
