generate_parametric_feature

Build one of MetaForge's named parametric features (bolt_pattern, a plate with a circular bolt-hole pattern, or rib, a triangular gusset) from typed parameters in a FreeCAD session, check it, and commit it with its parameters so a later change becomes a linked revision. Use when the user asks for a bolt circle, a mounting plate with N holes on a pitch circle, a motor-face or flange hole pattern, a gusset or stiffening rib, or asks to change one parameter of such a feature they already made.
