Possibilities of programming circular movements
The control provides a range of different ways to program circular movements. This allows
you to implement almost any type of drawing dimension directly. The circular movement is
described by the:
• center point and end point in the absolute or incremental dimension (default)
• Radius and end point in Cartesian coordinates
• Opening angle and end point in Cartesian coordinates or center point under the
• Polar coordinates with the polar angle AP= and the polar radius RP=
• Intermediate and end point
• End point and tangent direction at the start point.
