Smaller CAD developers -- less beholden to the Windows monopoly -- have been rewriting their code to make it portable between operating systems. StreamSpace is one. The latest to come out of stealth mode is Bricsys.
CEO Erik De Keyser provides a full explanation on the French-language Ubuntu forums. In brief:
- Brisys began a rewrite of Bricscad four years ago, to make it independent of the ITC.
- The Windows version will be completed by the end of this year.
- That will be followed by Linux in 8-10 months, and last of all, Mac.
- The new CAD code is based on WX Widgets.
- Because many third-party developer depend on MFC classes, Bricsys added it; the result is two code streams.
One note from me: just because Bricscad will run on Linux, don't carry the false expectation that it will be available at no cost.
