Thanks for the responce Jack.
We have county GIS maps and I believe even the sewer in autocad for the borough I'll be working on. I'm a web designer/photoshop guy at heart so I understand the layer schema and setting features. I checked out a book at barnes and nobles lastnight and looked at their example of installing pipe lines, but they already had valves in GIS they were just connecting lines and adding attributes.
All in all i'm starting to get a grasp for this project and your responce didn't bring up any new hurdles so I think I'll dive head first in this project once the software is installed next week.
My first task will be overlaying the autocad in arcview and digitalizing the pipes i guess. We have one planner at a different office who uses arcview but the distance will probably make online help just as fast and less of a hasle.
Again thanks and it looks like I'll be around this community a lot now.. which it seems you guys could use some active posters! Too bad they don't teach us these programs in college - not autocad or arcview, just stupid ones like solidworks,matlab, and statistics programs. I'm going to research the "serving on the web" you mentioned as that seems like something that would interest me.
