Need help with industrial spiral staircase layout V18 Platinum

Trying to layout this using the helix tool as a path then using sweep but the channel "side rails" are not coming out symmetrical. I put the helix centered between the channel profiles assuming that would be the most accurate but it's not forming correctly. Autodesk has an "app" called advanced steel where this stuff is automatic, I didn't see where Brics had anything comparable in their 3rd party store. Does anyone know of a program that might work or advise me on a better way of laying this out? See attached pic for reference, thanks!

  • Using the _Sweep command you typically do not have to align profile entities with the path. The command will do this for you. But selecting the correct basepoint is usually required.

Origami is the Japanese word for paper folding. ORI means to fold and KAMI means paper and involves the creation of paper forms usually entirely by folding.
