Then use Construct / Loft to get this scar-free result:



A couple other notes - MoI doesn't seem to be doing too good of a job of making the display mesh for some of these pieces, some things look more jagged than they really are. That's something that I want to tune up more in the future but it might not get better until after V1.

EDIT: oops, didn't see your last post in time, well here you go anyway! :)
