FreeCAD if could after years of development wasn't here, for me FreeCAD is a failed open-source movement, however, maybe it survives, I don't know, but I don't want you all after years have something

I'm not making the claim that meshes are the be-all and end-all. There is a time and place for a more parametric solid modeler (mechanical parts manufacturing, for instance). One program cannot suppor

@Moult I think I could use your gbXML exporter quite easily in FreeCAD... Would you be interested in trying to make it Blender-independent? I'm thinking in FreeCAD it could be fed with a list of Arch

F-osarch same for freeCad and so on.

* List of views and sheets and annotations will be kept "vendor agnostic" (ie. non Blender specific) for forward-looking IFC and FreeCAD interoperability

Okay we now have something up and running in FreeCAD!

@yorik by the way, not sure how much FreeCAD uses the geometry iterator in IfcOpenShell, but the iterator now has an includes/excludes argument to whitelist/blacklist elements to process :)

Note that on the freecad side we also have already some ways to import parts of ifc files (the "IFC explorer" tool in the BIM workbench). The main difficulty is to figure out what yo

In any case this is a slippery area, there are many IFC cases that don't translate 1:1 to neither Blender or FreeCAD (or Revit for that matter :D ). But circles are a convenient thing to support since

There is not much work needed in FreeCAD to be able to export such IFC files with members and nodes, basically most of what's needed is there already. We can already build beams and columns with a &am

Yes it is OK.

Am I right to think that we are not ready to author these IFC files in blender or freecad yet? I imagine that indicating fixity and connections has a special procedure.

Obviously if we compare Freecad with archicad, librecad with autocad and 3dsmax with blender. Coming from the commercial side I will say: "The opensource is still lacking things to get to the

That's a nice answer @Moult ! It would fit almost 1:1 for FreeCAD too :D

There is a lot of ambiguity and "dialects".. i spent a lot of time to address specific revit things in freecad, for ex. I like a lot that blenderbim is resetting the game, somehow..

@avico agree with @Jesusbill 's conclusion - there is ambiguity in the IFC spec, and BlenderBIM is playing catch-up with the FreeCAD flavour :)

Around this question, I am testing blender bim addon and get error importing IFC files. The model I use was generated with Freecad 0.18 and import was successful with addons versions 200413 and 200428

The bcfplugin Python library was initially created by Patrick Podestplatz here. Back in December last year, I proposed that the library be converted into FreeCAD-agnostic so that it could be reused in
