I have recently been asked to learn the Pressure Network part of Civil3D for an upcoming project but there are a couple of things I'm having trouble with. I will need to create approx 25km of water main supply pipe. I have worked out how to create pipes manually and assign the entire line to a pre-designed profile instead of offsetting from surface model with no real problems. But for the length and complexity of pipe involved the "Create pressure network from object" tool would probably speed things up enormously. My problem is that although this tool adds bends etc with ease, it does not seem to allow for pipe deflections at joints. ie. if the bend is actually 46 degrees it does not simply allow for a 0.5 degree deflection at the joints at each end. It instead realigns the downstream pipe and introduces 11.25 bends here and there to fix it's mistake. Also the same with straight pipes that might have a 1 degree deflection somewhere to follow road alignment. Instead of simply allowing the deflection between straight pipes, it introduces an 11.25 bend with deflection at it's joints over and above that allowed in the parts catalogue. Is there a setting or a box to be ticked that I am missing? Or am I destined to do all of the design manually? Any help will be greatly appreciated.......

I am having problems creating my pipe network in Civil 3d 2011. A previous employee created a pretty comprehensive list of pipes / structures and I thought I was doing the right thing by dragging and dropping from one of his drawings into my drawing. However I can see the list (in the prospector) in the new drawing but can't do anything with it. I can't edit it or add to it. I get the following error: Unable to edit network part. Required pipe network catalog(s) not set: Metric Pipe Catalog. I know the parts list was created in a previous version of civil (prob 2009) so I am not sure if that is the problem or if I am missing a step. I set the network catelog but that doesn't seem to have made any difference. I can even see the cad drawings within the catalog (C:\ProgramData\Autodesk\C3D 2011\enu\Pipes Catalog) Am I correct in thinking it should be as simple as copying the parts list from another drawing or is there more to it than that? I would really appreciate anyone's help on this. Unfortunately I am the only one in the office using this program and everything I know so far is from a tutorial. Thanks for your help in advance. Sooz
