Framesmith CAD Draws Bicycle Frames at Real Tube Diameters

Field notes

The tool accepts geometry in interchangeable forms such as bottom-bracket drop or height and saddle position from the shell or clamp. It applies Reynolds and Columbus specifications, including material and butting information, then updates a mass estimate as segments change. The workflow extends to a separate fork board, fitted-tire clearance views, J-bend and straight-pull spoke calculations, DXF output, and printable miter sheets with a 50mm scale check.
