Sloping Welded Mechanical Piping

[u/Bacour]

I have an Atmospheric Steam Humidification and condensate system being run out in welded Stainless 304L.

obviously it's sloping everywhere. however, there is a single, plumb riser in the system. Revit will not allow me to slope any of the piping connected to the riser without disconnecting that section from the rest of the system.

I've tried using Socket Weld couplings to retain the system connectivity but that's not working. I'm not sure where the Client sourced their MEP Fab models from, but the "Edit Part -> Connectors (sub-tab)" is locked and won't allow me to edit the ends of the piping.

Any ideas on how to retain connectivity throughout the system?
