A 12d Model app to add basic properties of a trimesh, such as volume, surface area and centroid, as attributes on the trimesh. This allows such 3d solids to be more easily and conveniently exported to other software as part of a BIM process.

Features:
- Full source code included
- Volume (only valid, closed trimeshes will have a volume)
- Surface area
- Closed state – is the trimesh closed?
- Centroid XYZ
Currently, this adds the attributes as string attributes to the same trimeshes selected. This means that the trimeshes cannot be read-only (e.g. from shared data). In the future, I’ll try to add in a target box, so you can copy or move to a new model.
