I am George Montgomery. I am a retired mechanical engineer with an interest in creating duct work in FreeCAD and CFD analysis there of.

This is a really interesting use case of FreeCAD:

and initially used BIM workbench of Freecad as I already have used Freecad in the past (they moved to 1.x already ;) ). I then found the IFC approach of Bonsai very appealing and that is why I start
