I am new to ss4. In fact, it has been a few years since I've used Inroads. My normal workflow for roadway design would be to import my alignment and my surface, create a profile and create a vertical alignment. Normally, I use the Evaluation/Create Profile to do this followed by the vertical geometry commands Unfortunately, when I try to create the vertical alignment on this profile, it won't let me. It tells me to Open Profile Model. When I try to do this, I get a useless grid that doesn't even show my surface. What am I missing here?
Thanks for the help.
