just started looking into civil 3d 2021 and the pressure pipe runs. I create a new parts list, from the PVC Material. When i ran the add new pipe run, it would not add the bends to the pipe run. If i used the preloaded part list water and ran the new pipe run, it would add the bends. still new to pressure pipes. looking for insight into why it only works for Autodesk part list and not a new one. thanks
