Scale an edge loop to match another I were trying to scale edge loop A so it would be the same size as edge loop B:



Intuitively I scaled and snapped like this:



But now A is slightly bigger than B.

My snapping settings and pivot point look like:



I fiddled with these settings for a while but couldn't get it right. I looked up LoopTools but it seems to for more complicated operations. Is there a simple way to make A just as big as B?
Just make sure you are constraining the scale to the X/Y axis. For that, hit Shift+Z after s.
