Questions

Are these structural CAD blocks free?

Yes — free to download and use in personal and commercial projects, with no account and no attribution.

DWG or DXF — which should I download?

DWG if your CAD opens it natively; DXF for everything else — cutters, CAM and open-source CAD. Both carry the same geometry and layers.
