I have been using pressure pipe networks for yard piping quite a bit lately and need more options as far as wyes and valves. While researching how to create the parts I need and import them I've realized that there are already categories for many of the parts that I'm looking for in the content catalog editor. Ive attached a screenshot of the editor when i open the catalog from path C:\Program Files\Autodesk\AutoCAD Civil 3D 2013\en-US. Several categories are listed but nothing is listed in the parts section under any of them. Is there a way to update this catalog with the current parts offered with the civil 3d? I currently am able to use cap/sleeve/bend/cross/reducer/tee/plug but need to have wye and valve and possibly hydrant. Any help would be greatly appreciated. Thanks
