I generated a custom fitting (technically represents multiple fittings (thd Half coupling, thd dielectric nipple, female x copper adapter) to show the connection between black carbon welded pipe to a soldered copper pipe. I had no issue while placing it in the drawing by connecting the HC end to a welded tee but when I tried to connect the copper pipe to the other end, it erases the fitting and fills from the tee with copper pipe.
Is there a setting within the custom family that is wrong, or is it referring back to the routing preferences and seeing that it can complete the route without using the custom fitting?
Note: I have the same issue when manually placing flanges around lug pattern valves and having the system at some point re-evaluate the route (when trimming, extending or something else with the pipe) and eliminating the flanges around the valve.
Let me know if there is any further clarification required and thanks in advance for the help.
