I am using C3D 2012. I have a pipe network catalog located on our office network server. I have a pipe size shown as 15" that is incorrect, it should read and label the pipe as 16" (see attached image). I don't know a lot of the workings how to edit this from 15 to 16 inch and what I need to do to get it correct for the other C3D users in the office. If some one has step through directions it would be much appreciated.
