I´m not able to create a curve

Dear people at the Rhino-forum,

I have an question and hopping for help.
As I try to create an circle with curves, I pressed the Enter-button to Close the curve.
But instead of the curve get clossed, the curve disapeared.
What is my mistake?


Hi Sebastian - a couple of things -

  1. Make sure to update your video card drivers from the Nvidia/AMD/Intel web site to the latest available,
  2. If that does not help, open Options > View > OpenGL page and un-check the setting for ‘GPU tessellation’.

Does either of those help?


Hi Pascal,

I have installed a new Driver. Now the curve not disapear.
