Are there any existing architecture datasets or datasets with.3dm files?

I feel like the answer is no, but just thought I’d ask in case someone is actively creating such a dataset or knows of such a dataset.

I know there is FloorPlanCAD (https://floorplancad.github.io/) for 2d plans, or ShapeNet (ShapeNet Dataset | Papers With Code) and similar for 3d models, but it seems architecture-specific (not industrial/product design or random collections of everything on Sketchfab) datasets are less common.

Would appreciate any input. Thanks!
