We have added a new Tolerance option to the control window of the following tools in the Evaluate palette:
This tolerance is available when Visual is checked on. It defines the quality of the visual curves independently of the tessellation tolerance. This way you can set the visual tolerance to a smaller value to get better quality visual curves, without reducing the tessellation tolerance used for shading which could negatively affect performance.
Left: visual tolerance = 0.1 mm. Right: visual tolerance = 0.001 mm
The same visual tolerance value is used for all three tools. The default is 0.01 (millimeters). Modifying the value in one control window changes the others. If a large number of surfaces have visual curves, then small tolerances will slow performance. Increase the tolerance to improve performance.
