Im new to this cad thing so im learning as I go. What I stumbled on is a feature that smooths the rough curves. The files I imported from here will open and smooth fine. The same files I open that I have saved from my previous program will not.. I have tried all different file types settings and nothing works. The first two pics show how it works. See how after I highlight it the points are outside the line where it needs to be to smooth. I simply click twice and it cleans it up. The third shows even though the points are there doesn't give me that option.
