Eazy-Draw claims to be able to import AppleWorks Draw (and Paint)* files, as well as ClarisDraw, MacDrawII and MacDraw Pro files, as fully editable vector graphics.
A single user licence is US$95 for the download version, a nine month trial is available for US$20, or you can download a fully functional demo (limited to creation or import of 'about 20' files).
Learn more at the Eazy-Draw website.
I've downloaded the demo, but won't have an opportunity to look into it for at least a few days.
Regards,
Barry
*Limited or no editing is possible for AppleWorks Paint documents and other bit map objects embedded in Draw documents.
