We are attempting to utilize the Pressure Pipe Network system that was introduced in Civil3D 2013 (updated in 2014), but we have hit a bit of a setback. Out of the box the system is very limited in the fittings or "appurtenances" as Autodesk has named them. I have seen a good number of detailed how-to's on creating these object, but I do not have the time or the labor hours to create an entire library with all of the different fittings and sizes we would need for any given project. I am wondering if anyone has heard of or seen any 3rd party add-on libraries for this? I have heard they may be out there, but have had no luck finding them. Anyone in the loop on this? Thanks!
