Sweep Function Help

[Anonymous]

Hi, I'm relatively new to autodesk inventor but I am trying to create an stl file to 3d print. Here's my problem. I'm playing around with the sweeping tool at the moment but I always seem to get an error when I try to  sweet a shape along a closed path. Would anybody know how I can fully close this path? I know I could use an offset plane and extrude a circle along one piece but is there a cleaner/more efficient way of doing this?

I think that you're on the right track.

I would make this out of from-to extrusions to workplaces set at the corner angle, perhaps with a sketch block for the profile.

More steps, but more robust if you want to change sizes later.
