Floor-plan Importer
A Blender add-on that reads floor-plan data and builds the geometry, so the plan is still editable as a scene afterwards.
Blender add-on development. Python import and geometry construction in the OpenArchSpecs context.
The import builds geometry you can move a wall in. That's the whole test, and a mesh dump fails it.
The importer, the interface and the geometry helpers are separate Python files, there's a sample plan in the repo, and it was built alongside OpenArchSpecs, so that project owns the file format.
State
A working importer with sample data and a short guide to the format.
