You don't give us your AC version. If you have a newer release, then just use the Morph tool to create the profile and extrude it. Otherwise, create a complex profile to match your profile - and duplicate it in the Profile Editor as necessary for your entire sun blind... and then extrude it with either the beam or the wall tool.
