Meaning
EXECTAB: Predefined procedure to execute a contour element
<contour table>: Name of the contour table
<contour element>: Number of the contour element
Example
Contour elements 0 to 2 in table KTAB should be executed block-by-block.
Program code Comment
N10 EXECTAB(KTAB[0]) ; Traverse element 0 of table KTAB.
N20 EXECTAB(KTAB[1]) ; Traverse element 1 of table KTAB.
N30 EXECTAB(KTAB[2]) ; Traverse element 2 of table KTAB.
3.24.6 Calculate circle data (CALCDAT)
With CALCDAT, you can calculate the radius and the circle center point coordinates from the
three or four points known along the circle. The specified points must be different.
Where four points do not lie directly on the circle an average value is formed for the circle center
point and the radius.
Note
Calculation regulation for the averaging
The arc calculation is performed four times:
1. With circle points 1, 2, 3
2. With circle points 1, 2, 4
3. With circle points 1, 3, 4
4. With circle points 2, 3, 4
The values of the circle center point coordinates abscissa and ordinate are calculated by
adding the abscissa and ordinate values of the four arc calculations and dividing by four.
The radius is calculated by forming the root from the sum of the four radii from the arc
calculations and multiplying the result with 0.5.
