Hi Will I see - but how would you expect a specialized command to create that stuff to work? It's hard to make a specialized command for something that is not easily controlled by specific parameters...

How did you create that ribbed type design in the first post, was it by having several sweeps that were then booleaned together?

It could possibly be easier if you built the ribbing into the profile curves more directly so that the sweep generated the final shape right off the bat, see this previous post for an example:
