Another solution is to do something similar to OpenSCAD's language but create our own sort-of-DSL that's really just a bunch of clean Python functions that is IFC based. This would mean that arcs / ci

CAD Sketcher (which is similar to the FreeCAD solution, as they both use the same solver) also doesn't quite give all the necessary functionality, like visibility depending on booleans, or loops / arr

Or maybe Blender is the wrong tool for this? What if this was implemented in FreeCAD instead? They have the parametric solver, it can be scripted, it can connect to BOLTS, and it can export out true c

Most proprietary software come with an asset library. There has been a renewed interest in the BOLTS project, a technical database of structural standards that is shared between OpenSCAD, FreeCAD, and

I'm less keen on Sverchok, given that a Sverchok dependency means that breakage is a bit more likely to happen (and has happened a few times already on Ladybug Tools) compared to pure bmesh scripting.

Bolts is a little dead (after all tech spec dbs isn't the sexiest project) but it's also the better than nothing, and means any work we do is already half integrated into FreeCAD and OpenSCAD so it be

I used @brunopostle 's rpm for use in FreeCAD on Fedora 36.

Yes, the same occurred to me today. Regarding FreeCAD, it can be straightforward to pick something from the wiki as the license is already known (CC BY 3.0).

A bit confused by that post, I see a github issue which links to the freecad forum I expected to see code or data :-)

2. Is it possible to make it "pure" ifcopenshell, so it's agnostic and the same script for example could be used in FreeCAD?

When I saw what Freecad could do (especially after it added hatching) and BlenderBim, I was a convert.

how to pass to topologic multiple selections of FreeCAD scene objects.

NativeIFC / BlenderBIM integration in FreeCAD

(potentially made using BlenderBIM Add-on, or FreeCAD, or WebIFC, etc) then I could get parametric Revit objects, smart cost-schedule or sequencing connected elements in Bexel or Synchro, a ggIFC gra

However regardless of how the geometry is generated for IFC (Sverchok, script, Blender geometry nodes, Blender drivers, etc) I think it's still a good idea to have a spreadsheet of their nominal dimen

For those reading along, there is now a GitHub repo -> https://github.com/yorikvanhavre/FreeCAD-BlenderBIM

Then all we have to do is fill out a spreadsheet for different parts of the world (I can help for Australia, maybe @theoryshaw for the US), and create a little geometry generator based on it - it coul
