Glad you found it useful guys.

I thought the same thing when, after reading your latest mini-tut, I discovered the 'Revolve by profile tool', which I had never even noticed - and is a huge time saver since it avoids duplicating and placing multiple profiles, when achieving the same effect with the Rail tool.

Regarding command input: I use it all the time with "rebuild" and "merge" - the former especially, because MOI still has a few hiccups when it comes to chamfering, lofting, blending compound-surfaces.
Rebuild, with "keep corners" disabled is also a great alternative to chamfering curves, although I wish point placement was more adaptive to reduce point counts and corners did not need constant fixing:
