Does anyone know if it is possible to create a double barrel pipe in the parts builder? I have been trying and have been unsuccessful. I have noticed that hydraflow allows you to select the number of barrels in each pipe run, but I can't find any reference to the number of barrels in Civil 3D. Take a look at the attached. This is our company standard style for displaying a single barrel pipe. We typically show our double barrel pipes the same way but two pipes side by side with a little space between them. And we also make the inlet boxs bigger too (that's not a problem thought). Can anyone help with developing a style for this type of pipe?
