Is there a way to save the DxDesigner v9.3 to an earlier version?
AFAIK it's not possible
No, but PADS Dx9.3 designs may open up in 9.2, it depends on the features used.
Also if you recently updated to 9.3, and find you need to go back, a backup copy is made at the point the design was updated. Contact support to learn how to retrieve this copy.
