Would the nodes that fall under Fitting only be displayed as a selection if 2 or more runs intersect?
You may be running into a problem I had with the utilities module that means that fittings can only be added to pressurised sewer systems, not gravity sewers. at this point in time I have had to use the pressurised system within the utility module as I have a lot of fittings on the runs.
I did raise this with Trimble back in September, not sure anything has changed though as I never got anything back.
Not sure that I understand the question - you can select any Node in a Utility Network from the project Explorer Tree or by Clicking on them graphically - when they are selected they are selected - not sure what you are asking here.
A Utility Node can be used in 1, 2 or more Runs - in the case of a Fitting that could be a T or an X fitting for example.
Can you give me a little more detail Layne?
