Teams can design production assemblies in Onshape and use VIZON for quick concept parts, AI starts and presentation of STEP files.
Yes, through STEP. Export STEP from one and open it in the other.
Not with mates. A VIZON file can hold several parts, and STEP assemblies open in the viewer and Studio, but assembly design belongs in a full CAD suite.
It runs in your browser, so trying it takes a minute, not an install.
