I come from a SolidWorks environment so my transition to ViaCAD has been difficult. I have a couple basic questions that hopefully have a simple answer.

1. In SolidWorks, you make a sketch, dimension it, then extrude or revolve it to make a part. If you want to make changes to the basic shape of the part, you go back to the sketch, which is parametric, make changes, and the model updates to the sketch.

In ViaCAD the sketch does not appear to be parametric, I can't dimension it for future reference, it does not "stick" to the model if the part is moved, and it does not update the model if you change it.

2. In SolidWorks, to make an assembly, you open an assembly model, when you assemble parts, you mate faces or surfaces or points and they stay mated that way.

In ViaCAD, I don't see an assembly mode, and when I assemble parts by faces or surfaces or points, they don't stay mated the way I put them together, they move around.

What am I missing or doing wrong?

Thanks,
Dave
