Validate in Part Builder

[dkaven.165530]

All,
I just started to work with the part builder in Civil3d 2008. I was able to create a structure and it seems to look proper with the the dim's and the constraints etc. But when I go to validate the part I get an error.

The error reads as follows:

Error: part type parameter not validated
Validation summery--level 1 errors found.

Is there a way to find were the error or what the error is?

Thanks
