In fact, if the fractional or absolute control parameter is too small, the mesher itself may
take an inordinate amount of CPU time to compute the preview mesh. If a too-small resolution parameter is entered accidently, use the escape key (ESC) to abort mesh construction.
To illustrate the effects of the Max Turning Angle control, a circular hole will be cut
in the surface presented in Figure 6-4, resulting in the following default mesh (Figure 68). Although some of the turning angles around the hole are smaller than the default value
of 45 degrees (especially as needed to encompass the thin section above the circle), the
maximum turning angle is visible at the right section of the circle’s circumference. The
“turning angle” is the angle that a straight line segment “turns” into the next straight line
segment as the segments pave a 1D curve.
