ANGLED |
Correction angle. When calculating the parabolas, the end angle results mathematically unambiguously from the given values. Nevertheless, it is possible that accuracy problems may occur. An error in the angle can accumulate. The program recognizes this situation and corrects the end angle by adjusting it to the angle of the following line. |
