@bitacovir correct, FreeCAD does the same ;)

like FreeCAD ;)

I added FreeCAD files for @Moult 's second test (mapped items) which I'm happy to say FreeCAD passed easily ;) and added a third test (extrusions of circles and rectangles), which of course BlenderBI

In any case, FreeCAD's behaviour is not illegal, so I'm now supporting it :) https://github.com/IfcOpenShell/IfcOpenShell/commit/bdf17e5c122720c64f048af17c3cbff1ea4ec582

Great! @Moult 's example is super interesting because it combines both "physical" model and analysis representation. I'll try to do that as well in FreeCAD. To resume what I found ou

It looks like Belgacem Nedjima https://github.com/NEDJIMAbelgacem will be working on the QGIS 3D engine including export. Might result in easier methods to get data back and forth from Blender/FreeCAD

@magicalcloud_75 that's what most apps do (FreeCAD included :/ ), when you have an object that either is a straight extrusion, or made only of flat faces without curved borders, they usually go as suc

That's awesome! In FreeCAD, structural elements like beams and columns already contain a linear representation. So far, this isn't exported to IFC, though. I'd be glad to work through that at some poi

Exactly! There is something interesting about this here: https://blenderartists.org/t/freecad-sverchok-subd-to-nurbs-require-coding/1218702/26 I have yet to dig a bit further there...

We could make "empty" buildings have a default placement in FreeCAD's IFC export, it's not a big deal, but it seems to me we would unnecessarily be adding superfluous information to

equivalent to the spatial tree. It looks like FreeCAD does not honour this implementer agreement, resulting in that error.

Each software SHOULD find that who are their main users? So, FreeCAD is popular in which industries? If you ask me I say in PLM area than BIM area, and those who are work on fabrication, etc, so peopl

Your claim that FreeCAD has a disadvantage because "it always ends up as a B-Rep" is false. FreeCAD is perfectly capable of producing solids.

When some people talk about FreeCAD's disadvantages, one of them is "It always ends up as B-Rep"

I'll try the files in freecad too, i believe that should work out of the box!

But there is basically always these problems with meshes, 1) there can be holes and 2) curves are faceted. I think closing holes is not too complicated, even freecad does it ;) but i'd like to try to

@ReD_CoDE The part of Homemaker that places roofs, doors, windows etc.. is entirely procedural.

I'd like a lot to port this to FreeCAD as well!

There is something to keep in mind in FreeCAD, with the default settings, all objects in the IFC file as recreated as editable (ie. their extrusions are recreated, etc). This is very inefficient, and

Yes. I know. But that means your FreeCAD installation works similar to pre-compiled version...
