If I have a duct network and want to change the duct system of this network I always need to click on a straight duct to change the system. Why cant I click the duct components and change the system from there? Sometimes we have areas with purely special geometric duct components without any normal round or squared straight ducts, and we always need to create an extra normal temporal duct just to change the duct system. It would be easiere if we could just select the duct components and change the system from there.
