Circles not circular

[rlajoie 0]

When I try to print a circular feature, it shows in cura and prints as a circle with straight lines used to make a circle.  It doesn't do this all the time but way to often.

A circle is never a real circle in 3D printing, it is built from polygons. So in your design software, you have to search for a setting with which quality you want to export the file as STL. When you choose a lower quality then you see each polygon if you choose a higher setting, then much more polygons are created to describe the circle and then it looks round as it should.
