Yeah. OpenDWG is great for all of the commercial packages, but terrible for any that are open-source. You are correct that opening legacy files is a big problem for linux cad programs, particularly open-source ones. Even qcad is hindered by only being able to open dxf files. One of the things that I am trying to do with the uber-converter project is to get a working open-source dwg converter implementation. http://ericwilhelm.homeip.net/uber-converter/ With Varicad, there is a bigger problem: you can't import/export dwg's with solid models because the openDWG library doesn't handle ACIS data. I wrote to Spacial asking for the ACIS spec, and they kindly told me to go figure-it-out myself. A great attitude toward interoperability! So, is the problem with Linux cad programs, or is it with all of those other programs? --Eric -- A counterintuitive sansevieria trifasciata was once literalized guiltily. --Product of Artificial Intelligence
