How do I change the units used on deisgns in VeSys 2.0 Design from inches to mm's?
You can change the default unit in VeSys 2.0 Design from the project preferences;
File -> Project Preferences
Then select Diagram from the VeSys 2.0 Design node.
For metric users change the grid spacing to 2.5 (from 0.25) and unit to mm (from inch).
