Help! Pipe Network Question

[SwChilly]

I'm using AutoCAD Civil 3D 2010.

I'm new to pipe networks so bear with me. What I'm trying to do is create pipe network from objects. So I go to Pipe Network> Create Pipe Network from Object> then slect my object.... but what if I want multiple objects under the same network?

If I call multiple objects the same network name, it just adds a counter (ex. Proposed Water, and Proposed Water (1)). I don't want that. I want them all under the same network but different pipes.

One of our older drawings have mutliple pipes under the same network.. Help!

I've got another one... is there a way to move a pipe from one network to the next?

Oh! Also... how do I add a structure to a pipe? The tutorial is way confusing.

Thanks in advance!

What objects are you using to create the network? You can only use Lines, Polylines, Splines, Arcs & Feature lines

from Help

Create pipe networks from existing objects in your drawing.
Using this method you can automatically create a pipe network from the following types of entities:
Entity Description
Line Creates a pipe network from a line that you selected. The pipe network is inserted as a straight pipe with structures at each end.
2D polyline Creates a pipe network from lightweight or heavyweight 2D polylines.
2D spline polyline Creates a series of straight line segments using fit points to define pipe endpoints and structure locations. For more information about fit points, see the AutoCAD Help.
3D polyline Creates a pipe network using vertices in 3D to define pipe endpoints and structure locations. Arc Creates a pipe network from an arc that you selected. The pipe network is inserted as a curved pipe with structures at each end.
Feature line Creates a pipe network from a feature line.

using Create Pipe Network from Object will create one network using the vertexes to insert structures with pipes between.

I've got three polylines.. but I can't click them all to make them under the same network.
