With all due respect and not hint of sarcasm, I think that you are missing a little practice with this tool and have excess "AutoCAD Attitude."
If I can prove to you that it is the same number of steps in ArchiCAD, will you promise me that you'll try it out? Perhaps this doesn't work the same, but from what you've explained, it seems to be comparable.
Make an ArchiCAD keyboard shortcut to activate the offset function.
Trace the existing polygon to be offset with a spacebar magic wanding - this is comparable to selecting the element in AutoCAD. OR draw your polyline. When you exit the drawing function, it will now follow your cursor click position for the offset amount.
It will also expand the open or closed polyline proportionally.
I don't know if the AutoCAD makes the offset with a copy of the original polyline or not. ArchiCAD will leave the original unaltered.
I haven't had the benefit of an AutoCAD education. Perhaps it has more variants, but the ArchiCAD tool seems to work in just two steps as you need.
Try it out.
