G'day! From this discussion I thought it would be a great idea to organise three virtual OSArch meetups :)
1) A show and tell hosted by @yorik , showcasing the incredible work done on FreeCAD 1.0, and the current state of the Native IFC workbench
2) A show and tell hosted by @Moult , showcasing how the underlying technologies interact in Bonsai with IfcOpenShell, Blender, OpenCASCADE, etc and some of the more recent developments in Bonsai. In particular to discuss how we can continue to have cross-pollination between the Blender and FreeCAD UIs that share IfcOpenShell and OCC under the hood.
3) A technical exploration by @aothms explaining some of the ideas being proposed by IFC5, why they are proposed, and possible technical opportunities and challenges.
Thoughts on timing and dates?
