Importing help

I'm new to using this software, but I'm in a aerodynamics course this semester and we use it. Because of this I was assigned to a senior design group where I would need to do CFD analysis.

I've imported a PRO-e CAD model in STL format and trying to create feature curves on it. When I go to Regions>Regions 1 and right click on feature curve>new feature curve> mark edges I get an error saying, "cannot execute action without a surface representation."

I've looked up in the tutorials how to do this and the screen shot doesn't look the same. When I try to do it, all I have is representations>geometry and from the tutorials I should have Representations>Volume Mesh> Region 1

Could someone point me in the right direction or show me where the tutorial is that could teach me? Thanks.

Did you import the surface to the parts level and create the region? The you should also have a mesh continuum, and hit the "initialize meshing" button first.

Sorry I figured it out. I was doing it wrong. I needed to import the CAD model as a .igs file and then create part then create region.
