These tutorials demonstrate how to work with the Part Builder features, which you use to design and model parts (pipes and structures) that are used in pipe networks.
If you have not installed AutoCAD Civil 3D to the default location, you may receive messages in the Event Viewer, indicating that pipe network part catalogs are not found. To avoid these messages, it is recommended that you follow the exercises in the order presented. Alternatively, you can reset the path to the catalogs by clicking Home tab 
Create Design panel
Set Pipe Network Catalog
