Coordinate systems can be pretty confusing, and there are a lot of options. Luckily, when everything is configured right, your transforms just happen in the background like magic. For those occasions when things aren't showing up where you expect them, here are a few good resources to look to:
- The help on Autodesk.com
- The Map 3D and Civil 3D forums (search before you post!)
- Spatial Reference (external site)
- This excellent explanatory article (external site)
- Wikipedia for a basic overview and good links (external site)
- A site with a fairly easy to read transform listing (external site)
- The EPSG guides have much of the source material. Number 7 part 2 may be the most useful.(external site)
Have fun!
