For many years I have been using American Small Business's DesignCAD 2D under the DOS feature of Win XP. For me, it's a dream CAD program altho having 50-odd annoying quirks--and today, it's totally obsolete. The file format is DW2. Can LibreCAD import that format, edit a/r, and then save it in its own format? If not, might it do so some day? Once I change away from XP I'm done for.
I could perhaps first convert to DXF but as I recall, before that I have to "vectorize" all the text and that's a pain in the neck.
