Hi Garet, yeah in cases where they're going to be getting in your way it tends to be good to get in the habit of either hiding or deleting the original construction curves right after you are done with whatever construction you were doing with them.

In the future this is an area that I'd like to tune up somehow, maybe by trying to put up some kind of selection popup that says something like "Curve or edge?" in this kind of situation where there is a separate curve and edge stacked on top of each other. It's a tricky thing to get working nicely though since it is one general goal of MoI to not annoy you a lot by popping up dialogs right in your face all the time...
