What is Buildref?
Buildref is a free engineering toolkit centered on an online Beam & Frame Calculator. Sketch any beam or 2D frame right in your browser, drop in supports, hinges and loads, and instantly read off bending-moment (M), shear (V) and axial (N) diagrams, support reactions and deflection — no account, no install. Export to PDF or share via link. The toolkit also bundles free STL/OBJ/GLB 3D file converters, an in-browser 3D model viewer, unit converters and engineering references. Available in English and German.
