When I draw any curve (line, circle etc) using the continuous linetype, the geometry disappears when I hit enter. If I change the linetype for the layer on which the curve was generated, the geometry will re appear. This problem has been present for the last three builds including build 2018-01-02. What’s wrong?
This may be a problem with your GPU driver. I would check to see if any driver updates are available. If that doesn’t work, you may have to disable GPU Tessellation in the OpenGL options page in Rhino.
