A free, browser-based tool for generating parametric engineering parts. No installation, no login — just set your dimensions and download a DXF, STL or PDF engineering drawing instantly.
Supports 20 standard part types across 5 categories: Plates & Shells (Flat Plate, Disc, Pipe), Structural (Bracket, T-Bracket, I-Beam, C-Channel), Shafts & Hubs (Shaft, Stepped Shaft, Flange), Fasteners (Bolt, Cap Screw, Nut, Washer, Pin, Key, Circlip) and Power & Drive (Gear, Coil Spring, Pulley). Every part includes a live 3D preview, weight estimation and a properly formatted title block.
Built as a mechanical engineering project — and left open for anyone who finds it useful.
