MicroMVDs and FreeCAD
Because the official buildingSMART MVDs aren't granular enough for projects, I've been developing MicroMVDs: https://wiki.osarch.org/index.php?title=Using_MicroMVDs_for_exchange_requirements - effectively they are unit tests for BIM data exchange requirements, written in natural language syntax but can be automatically tested.
The following seven MicroMVDs are stable, and at work are including them in BIM contractual documents.
- Project setup
- Model federation
- Element classes
- Geometric detail
Graphisoft has reached out to see if they can improve their score, so it'd be good if we can showcase the quality of FOSS in data exchange :)
