Hello,
This is my first post. I search this forum often to answer questions that come up in my office. I am running AutoCAD Civil 3D 2014.
I have created a pressure pipe network for a proposed water main. I have an alignment and a surface. I want the water main (pressure pipe network) to be 5 feet below the gradeline. I typically use the FOLLOWSURFACEINPV command but when I type it in it is telling me Select a valid reference surface to follow. But it won't let me click on the surface to select.
Does anyone know how to "Select a valid refecerence surface to follow" when using the FOLLOWSURFACEINPV command?
Thank you.
After finding this post over three times, I figured that I'd try and help.
I have two possible solutions to the "Select a valid reference to follow" message.
1) Select a pipe in the profile view, right click and select "Edit Pressure Network in Profile..." This will close the command. FOLLOWSURFACEINPV command should now have a valid surface selected.
2) Toolspace Prospector->Pressure Networks->Select network->Pressure Network Properties->Default Object Reference->Surface name. Select the surface to follow.
