In this video, a discussion between Moult and Dimitar, at the very last part, it is mentioned (again) the BlenderBIM features are ready to be adopted in FreeCAD.yorik wrote: ↑Fri Nov 26, 2021 11:41 am In the case of BlenderBIM, the way it work in Blender is: A Blender model is tied to an IFC file. If you add a new BIM object, that object is actually created as an IFC object first, then "rendered" into a corresponding Blender object. So your Blender model is always a mirror of the IFC content. When you save the file, both files are actually saved. You actually work natively on the IFC file.
Since BlenderBIM maintains a kind of "parallel model", in memory, the same kind of thing could happen in FreeCAD and who knows, BlenderBIM could one day work in FreeCAD too! Each FreeCAD BIM object could obtain its geometry from a corresponding BlenderBIM object.
There is a long way to there obviously, but that would IMHO be a fantastic path: FreeCAD could be used as a strict, 100% faithful IFC editor, the same way as Moult is going with BlenderBIM, and keep the loose, free BIM modeling paradigm it has now too. Best of 2 worlds
Topologic could be used the same way. For example, tolopogic is typically used to create spaces, that get automatically connected and arranged by sets of rules. We could have a set of Arch spaces, all derived/driven by corresponding Topologic spaces.
For these two things, FreeCAD needs to keep, together with the FreeCAD document, a corresponding other document structure (Topologic or BlenderBIM). I'm not sure how that could be done efficiently. Needs more brainstorming I guess...
Any idea if this is going to happen ?
