Certain projects require double s slip joint reinforcement and what our company does is make a standalone double s slip "coupling" that ends up being reinforced and creates the double s slip joint between two 60" joints of raw duct. We were trying to setup our database to draw rectangular duct that automatically adds couplings between straight duct and/or fittings using CID pattern 4522. This worked great, automatically adding the couplings between joints of duct, but when you view the development of one of the couplings it is blank. Is there a way to get the development of the coupling to show up so that we can apply reinforcement (Tie-rods) to it?
