Duct fittings in BlenderBIM (MEP)
Dear all,
I would like to create Fabrication-grade duct fittings in BlenderBIM. It is easy to draw in Blender with meshes, but how can I create parametric models? There is an example done in SketchUp:

For those who know Revit, I would like to know how to create Revit Family-like models in BlenderBIM.
I know Python and C# (though C# is not used in BlenderBIM, as far as I see).
Thanks.

AFAIK the BlenderBIM addon doesn't support that high level of parametric modelling natively. There are some builtin profile which you can tweak the parameters but you can't define arbitrary profile parameters. I may be wrong so anyone feel free to correct me if so.
There are other Blender-based possibilities, like Geometry Nodes (node-based, so it's not really as user-friendly as other tools), Sverchok (node-based too, and has a bridge to ifc with Sverchok-ifc) and CAD-Sketcher (which has a parametric workflow similar to other CAD softwares https://www.cadsketcher.com/)
@ccrabbit do you think it is possible to bound a shape generator to specific standard IFC pset? As BB does with doors for example
not an expert but i think the current work around intelligent ducts and fittings can be found...
ping @Andrej730

I understand that BlenderBIM has devised a way to make geometry to conform to IFC, but it would be a good modeling progress if the tools you are creating for Blender graphics could be converted :)

They can be converted. However you will lose the procedural aspect of it.
Not BlenderBIM, but FreeCAD :
