## About

Buildref is a free engineering toolkit built around an online Beam & Frame Calculator. Draw any beam or 2D frame in your browser, add supports, hinges and loads, and instantly get bending-moment (M), shear (V) and axial (N) diagrams, support reactions and deflection — no sign-up, no install. Export a PDF or share a link.

Beyond the calculator, Buildref includes free STL/OBJ/GLB file converters, a browser-based 3D model viewer, unit converters and engineering references. Available in English and German.
