Manufacturing / Sheet metal

Sheet metal DFM checker.

Stacks a thickness estimate on top of a bend-radius estimate, then groups individual bend edges into full bend lines for the flange-length and relief checks. The family most likely to need iteration of everything Buildable checks.

CheckWhat it doesStatus

Bend radiusEstimates local bend radius from discrete curvature and flags spots tighter than the part's own estimated gauge.Detected

Holes near a bend or edgeFlags holes punched closer than a few times material thickness to a bend line or the part edge, on an open flat-pattern mesh.Needs an open mesh

Minimum flange lengthGroups bend edges into full bend lines and measures each flange's own depth against material gauge, on an open flat-pattern mesh.Needs an open mesh

Bend reliefFlags bend lines meeting close together at a roughly perpendicular angle, the signature of a corner that will tear without a relief cut.Detected

Holes-near-bend and flange-length both need a genuine open boundary in the mesh to measure against, the far edge of an actual flat-pattern shell. A solid STEP or a watertight STL, which is most real uploads, has no such boundary, so those two checks correctly find nothing to flag rather than reporting a false result. Bend radius and bend relief don't have this limitation and run on any part. Automatic fixes for sheet-metal bend radius are on the roadmap; every check here is real and working today, detection-only for now.
