Even though it’s been quite some time since I released D2X, I still seem to get requests for it trickling in. The old codeplex project seems to have been ‘pruned’ (for inactivity, one would assume), so here’s a link to the last build I made:
A word of warning, however – It’s been a couple of years, so the version of the ODA libraries used to read the AutoCAD formats are quite out of date. The latest AutoCAD releases almost certainly will not be able to be converted.
I should still have the source on an old backup – I’ll post that as well when I’m able to find it.
Good Luck folks!
