Sketched Bend
The SheetMetalSketchedBend node folds the material on one side of a
sketched line across a flat face — the true interior fold. You author the fold line as a Line on the
plate; the half beyond the line folds up around a real bend region while the
other half stays put. bend_position defaults to bend-centerline (the
SolidWorks default — the line is the developed midpoint of the bend).
