Thank you for your response, Paul. I used the 3-point arc command as the other ones did not seem to work (they did not follow the projected curve). However, when I dimensioned it a reference angle dimension of (0.00) was created.
I used the chair in the factory assets under architectural > furniture and after sending it to inventor it is still in 2D. When I manually import that same asset in inventor to try and overlay it over the 2d version, I can't figure out how to align it.
