The drainage profile is created on the fly by the program the profile will start at the upstream node at its hydraulic center and go from there straight to the pipe connection point then down the pipe to the end or downstream pipe connection point then to the hydraulic center of that node and then onto the next pipe connection point. It continues in that manner to the end of the profile. The width of the node is a determined by where the pipes conncect to the structure and the hydraulic center. So if your pipes connect to each other then there will likely be no width or a single line representing the node.

All - thank you for the responses.
Nico - We work mostly in PA and NJ so I need to generate nodes that represent the standard drainage structures for those states. We tend to use the same handful of structure types so I was hoping to modify the *.x files provided with Powercivil. However, without an understanding of what the coding in the *.x files means I'd be shooting in the dark until I hit something. I'm looking over the FDOT training booklet.
Beebe - How do I modify the pipe connections so they connect to the nodes and not each other?

The node cells will have pipe connection points on them if someone has modified the cell library. Turn on Constructions in the View Attributes and look for points in the cell. If they do not exist then you would need to modify the cell library and add them in. The GEOPAK Drainage Help details the various Drainage Points that can be added to node cells to give hydraulic intelligence. Search the help for Node Cells to get a clearer detailed description
Beebe,
I found the Node Cells section buried in the Drainage Help. By placing circles around circular nodes the pipes are drawn to the outside of the structure, however, on rectangular nodes I've placed POINT ELEMENTS with the same class and linestyle as the circles and the pipes are still being drawn to the center of the structure. Any thoughts?
Assuming you created the point elements with the Linestyle and Class that was specified in the help then you updated the nodes in the project so that you could see the new point elements in the cell, then you would have edited the pipes and had them connect to the new pipe location points or point elements you created. Once you did all that you would then need to recompute the profile. To be safe you may also want to designate a hydraulic center point in your cells.

After playing around with this issue again this morning I found that one must use the From Node ID and To Node ID buttons to select the side of the rectangular structure which to connect the link to. I was only selecting the node from the pull down menu. I will have another post this morning regarding another issue I'm running into when trying to use a site model to set the node elevations.
Thanks for your help.
