Calculates radius and center
point of a circle from 3 or 4 points
(according to parameter 1), which
must lie on a circle. The points
must be different.

Explanation:
CALCPOSI
CALCPOSI is for checking whether, starting from a defined starting point, the geometry
axes can traverse a defined path without violating the axis limits (software limits), working
area limitations, or protection zones. If the defined path cannot be traversed without
violating limits, the maximum permissible value is returned.
INTERSEC BOOL:

VAR REAL [2]:
Result vector:
Intersection
coordinate,
abscissa and

Intersection: Calculation of
intersection
The intersection between two
contour elements is calculated.
The intersection coordinates
are return values. The error
status indicates whether an
intersection was found.
