How do a do a proportional scale in 2 axis?

Holding Ctrl should work, too.
I believe there are extensions that create circles out of segments that are the same length.

Is there some extension to unexplode curve?

Not quite, there is a plugin that will remake circles and arcs, as long as the segments are all the same size. I made this gif a while back to demonstrate the difference. [image]
