It took 4 min 7 sec to import in FreeCAD 0.19

I finally got the freecad 0.19 nightly snapshots for fedora (from this copr repository ) working by setting QT_QPA_PLATFORM=xcb in my environment. I also built ifcopenshell 0.6.0, is this the recommen

I also had no idea ladybug had moved so far out of dependency of proprietary platforms!!! That's really very interesting. I'd be very interested in exploring how to integrate this with FreeCAD as well

I try to advertise BlenderBIM to Ehsan Iran-Nejad (creator and maintainer of pyRevit) and community. Interest is awaken. Many of them are aware of FreeCAD and BlenderBIM.

FreeCAD is a solid modeler that as far as I know always ends up with B-Rep and Blender is a Polygonal mesh-based modeler

Or with FreeCAD through pyFlow. https://forum.freecadweb.org/viewtopic.php?t=36299

Freecad is a solid modeller and blender is a mesh based modeller. Getting IFC files to round trip between these very different systems without data loss is a good test of interoperability.

@yorik , can you put (2) cubes in your FreeCAD file, one extruding in the Z and one extruding in the y or x?

I open this topic to request features for tools we develop together, like BlenderBIM, FreeCAD, IFC2CA, etc

It sounds like @yorik's implementation in FreeCAD, my implementation in Blender, and Revit's implementation all ignore the rectangle profile def and use a regular closed profile. Maybe we can round-tr

Yes. I was thinking on jump between different drawings with hyperlinks inserted on the 2D drawing. Currently, you always need to open folders or click a list of links. But create this interactive draw

FreeCAD can export exactly that above, but last time I checked, Revit had problems reading the IfcRectangleProfileDef entity. So there is even an option to disable it in FreeCAD (all profiles are then

I'd be highly interested in trying to produce an IFC file form FreeCAD that is compatible with this structure...

Possible to roundtrip just this between Freecad and Blender, and maintain all the parameters through strict implementation?

With BlenderGIS (import/export shapefiles) and BlenderBIM (import/export IFC) it does seem like going back and forth is possible with Blender as the an intermediary. FreeCAD might also work as an inte

BTW I extended the script above a little bit and it's now part of freecad https://forum.freecadweb.org/viewtopic.php?f=9&t=46150

Other possible workflows once you have an IFC model could be import to FreeCAD (there is finite element analysis with calculix but I doubt you can do nonlinear dynamic analysis) and from there to Salo

It would be cool if someone develops a FreeCAD addon for wood structure analysis using Code_Aster.

By the way, @yorik 's sample Python script modifies the colour in FreeCAD - but this has similar downsides to the SimpleBIM solution (and the existing colour by property feature in the BlenderBIM Add-
