AutoCAD Civil 3D 2009 Survey Database issues

Just a brief alert for those of you using AutoCAD Civil 3D 2009 survey databases. I've encountered a problem where if I try to import a survey field book into a new survey network that uses existing setup and backsight points from another survey network, things go wrong. Please note that I am not using Vault to manage my survey databases, therefore I don't know if this is also an issue for those of you using Vault.
 
The program won't recognize the existing points you are trying to occupy, apparently because they are in another survey network (but within the same survey database of course), and will result in the following error message:

AutoCAD Civil 3D 2009 error message

 

The reason I am alerting you to this, other than it's not working correctly, is that I have had the field book input into the wrong survey network (the one where the existing occupied point number resided). This happened when I hit "cancel". Having your data end up in the wrong survey network is one thing, but it's very difficult to undo this process if this new data is intermixed with your older survey data (particularly if your field data has issues and was not completely corrected prior to being input). Also note that you may get unexpected results even if you click yes or no. And this also seems to create problems with survey figures being created.

The folks at Autodesk are currently working on this problem with me and I expect a resolution to this issue shortly. However, in the meantime I recommend the following:

  1. Make sure your survey field books are edited, appropriately corrected and ready to run. You can check this by setting up a "scratch" or temporary survey database (and drawing file) to test the input of your field book. Common issues are: incorrect setup/backsight points, duplicate point numbers, incorrect descriptions, incorrect rod heights and corrections to survey figure commands and descriptions. Basically, look where there is human input at the data collector prompts.
  2. Before you add anything to your project survey database, make complete copies of all the project files, particularly the survey database itself, so that if something goes wrong you can easily go back in time to where you started.

I will give you an update when I have more information and please leave a comment if you have experienced these problems or if you have anything to offer for a solution.
