Currently VP-UML does not provide facilities for merging projects nor copying diagrams from one project to another. We will consider adding this feature in the future release. By the way, VP-UML evaluation versions are fully-functional, the only limitation is it can only be used within the trial period.
Is there anyway to integrate two VP projects? or to copy one diagram from one project to another project? I am using evaluation version may be thats why I am unable to do so.
