Geometry functions
Identifier Return value Parameter Explanation
1. 2. 3.
CALCDAT BOOL:
Error status
VAR REAL [n,
2]:
Table (abscissa,
ordinate) of
points 1 to n
INT:
Number of points
VAR REAL [3]:
Result: Abscis‐
sa, ordinate and
radius of calcula‐
ted circle center
point
Calculates the center point coor‐
dinates and the radius of the cir‐
cle from 3 or 4 points
The points must be different.
INTERSEC BOOL:
Error status
VAR REAL [11]:
First contour ele‐
ment
VAR REAL [11]:
Second contour
element
VAR REAL [2]:
Result vector for
the intersection
coordinates: Ab‐
scissa and ordi‐
nate
Calculates the intersection coor‐
dinates between two contour el‐
ements.
The error status indicates wheth‐
er an intersection was found.

CTAB REAL:
Follow‐
ing axis
position
REAL:
Leading
axis posi‐
tion
INT:
Table

VAR RE‐
AL[ ]:
Pitch re‐
sult
AXIS:
Follow‐

axis for
scaling
Determines the follow‐
ing axis position to the
specified leading axis
position from the curve
table.
If parameters 4/5 are
not programmed, cal‐
culation is with stand‐
ard scaling.
CTABINV REAL:
Leading

sult
AXIS:
Follow‐
ing axis
for scal‐
ing
AXIS:
Leading
axis for
scaling
Determines the lead‐
ing axis position to the
specified following ax‐
is position from the
curve table.
If parameters 5/6 are
not programmed, cal‐
culation is with stand‐
ard scaling.
CTABID INT:

"SRAM",
"DRAM"
Determines the curve
table number entered
under the specified
number in the memory.
