HELP with Intersections, what does this Dialog Box mean?

I am still rather new to intersection creation in Civil 3D. I keep getting to the end and getting the same dialog box. Does anyone know what this means? Or what I need to do to stop it?


If I click the "Create Intersection", nothing shows up. If click "Specify Design Profiles", I am not really sure what to change. Any help is greatly appreciated!

When you created the intersection you should have specified two profiles which will be part of the corridor baselines at the intersection.  The software will adjust the secondary road profile if necessary to match the primary, but if the profile you selected for the secondary road is of the wrong type then it can't do the adjustment. 


Open the intersection properties dialog and check the profiles that you're using.

Apparently one or more of the profiles you are using in the wizard is getting it's data from a source other than a layout profile, such as a surface profile. Thus if the profile of a crossing aligmment changes, the profile from the surface can't move with it because it is set to use the surface elevation.

This happens when you don't have any Design Profiles, and you only have Surface profiles (probably EG). So it's asking you if you really want to create the intersection with the EG profiles.


Go back and create a couple Design profiles for your Alignments, and then start the Intersection Wizard again.
