Sheet Metal Master

15 sheet-metal tasks for ducts, pipes, intersections, heads, and bends—with local previews, fabrication allowances, saved projects, and ASCII R12 DXF export.

Sheet Metal Master is an on-device calculation tool for duct fabrication, pipe fitting, and sheet-metal layout. Enter measurable dimensions to preview patterns, define fabrication allowances, save projects, and export DXF files.

15 TASKS • Ductwork: round-to-rectangle, rectangular reducer, 90° round tee, rectangular offset, rectangular miter elbow, and rectangular tee • Pipe and vessel work: oblique round tee, equal-diameter round Y branch, segmented elbow, cone/frustum, oblique-cut pipe, and spherical-head gores • Bending: single bend, double bend, and box bend

WORKFLOW • Live result and flat-pattern previews • Welding, riveting, lock-seam, and manual allowances • Save, reopen, and update local projects • Share calculation summaries • Export millimeter-based ASCII R12 DXF files

Core calculations run locally on your device. The round Y branch is a field-fit construction. A sphere cannot be flattened without strain, so spherical-head gores are an approximation with a reported boundary-strain value. Always verify material, connection details, and a sample before production cutting.
