generate_cad_ir

Build a featured CAD part step by step (body, sketches, pads, pockets, booleans, fillets, revolves, patterns) as an ordered feature list, execute it through the FreeCAD session tools or one CadQuery script, then export a correctly named STEP and commit it to the twin. Use when the user wants a real part with holes, pockets, cut-outs, bosses, rounded edges, revolved or patterned features at stated positions, or when a simple parametric primitive from generate_cad cannot represent the part.
