OpenCascade Documentation

 * Roman Lygin's tutorials
 * Online class reference. This is the help data on-line for the last version that they offer this way, it is out of date but still helpful and often still relevant. It is perhaps more convenient that having to download a single large file, which is what you have to do for a more recent version.
 * The openCascade wiki

Roadmap
FreeCAD, though usable in certain areas, is at the beginning of a long way into the CAD mainstream. There is still a lot to do to reach a state where we can compete with commercial software.
