AWAL OP or not... has anyone else had this issue? I have a similar issue with connecting a Transition (CID 2)to two elbows (CID 22) in Revit. I need to put in a small piece of straight duct on each of the elbows, place the Transition on one of the little straight stubs, stretch it to the other straight stub so it adopts the size and offset. Then use the little blue arrows on the transition to stretch and "consume" the little stubs so that I have all three fittings connected. A lot of time wasted just to connect three fittings.
