We are attempting to impliment the Pressure Pipe Network system that came with Civil3D 2013 (also available and updated on 2014). The problem with this system is that, out of the box, it comes with very little in terms of fittings or appurtenances as Autodesk has named them. I have seen a number of how-to's on creating these objects, but I do not have the extra time to create a library of all of the fittings at all of the sizes that we could use on any given project. Has anyone seen or heard of a 3rd party add-on for this? I browsed the Autodesk website of add-ons and they had nothing. I was also told in another forum that the company Cadtechs offered such a library, but did not find anything on their website. Any thoughts? Has anyone found and is using such a library?
