Sheet metal Fold (SheetMetalFoldCmd): fold the base panel along a sketch line (followed when the sketch changes) or two points on its face; angle, bend radius and K-factor from the rule; the bend zone (BA = θ(R + K·T)) comes out of the existing sheet so the flat pattern keeps its size; the line at the bend's centre, start, end or on the mould line; the side holding a picked point stays (default the larger), flip folds down; flanges on the moving part ride along
