I agree 100% that the big point for a working oss cad is cooperation between different projects. But it is not three cad systems that can be combined. Instead it is possible and useful to combine e.g. 2d-engine, 3d-(csg/...)-engine, object database, gui etc. The power of open source is that this is possible. If you try to enhance a 2d app with 3d, add 2d cad functionality to a modeler, etc, you will have some thankful users imediately (that is why I would still like to see such cooperation in a way of easy dataexchange at least), but get a suboptimal design which will be hard to evolve. By the way, that is why I am so excited about brlcad - as it is a package of small tools and libraries that other apps could refer to, without the need to take what is not wanted or needed. So e.g. a 3d-project such as freecad could easily use all its functionality. Lars.
