As weldment? Is this better suited to a routed feature? I have a customer that is asking for us to design an equal length exhaust header for a small multicylinder engine (Racing Lawn Tractors!!!! FUN!!). Space is tight so I need to define the confines and rout accordingly. I thought I'd start with 3Dsketches to define the path and use structural members with the profile of the exhaust tubing I have, but I need to keep the individual header pipes to the collector as equal in length as possible. Is there an easy way to do this?
