The best option for any of us to help you is going to be to see what you are seeing. What you are saying, doesnt make sense from the way the program operates, so there must be something that is going on that you are not describing with words. Providing a screenshot would provide a thousand words and greatly help in giving us a direction of where you might need to go to resolve your issue. If the panel isnt there, if you type the _AeccCreateAlignmentLayout command manually at the command line, what does Civil 3D do?
