Geometric Entries

A variety of geometric information is computed by the postprocessor. This geometric information can be used as $PP entries. This provides for various methods of representing geometric information for different types of controllers.

The following describes the different types of geometric entries allowed in the $PP file:

ANGLE	Angle from start point to end point in degrees.
DIR0	Direction of arc, 0 if counterclockwise 1 if clockwise.
DIR1	Direction of arc, -1 if counterclockwise 1 if clockwise.
EA	End angle of arc in degrees.
LENGTH	Length of line or arc.
RADIUS	Radius of arc.
FRADIUS	This is the radius of the current arc/circle but it will be negative if the sweep is greater than 180 degrees.
SA	Start angle of arc in degrees.
SWEEP	Sweep of arc in degrees, positive if counterclockwise, negative if clockwise.
X	Current cutter position in X. Absolute or incremental depending on mode.
X1A	Absolute X coordinate of start point of arc, line, point.
X2A	Absolute X coordinate of end point of arc, line.
X2I	Incremental X coordinate of end point of arc, line.
XA	Current absolute cutter position in X.
XC	X coordinate of center of arc. Absolute or incremental depending on mode.
XCA	Absolute X coordinate of center of arc.
XCI	Incremental X coordinate of center of arc.
XI	Current incremental cutter position in X.
Y	Current cutter position in Y. Absolute or incremental depending on mode.
Y1A	Absolute Y coordinate of start point of arc, line, point.
Y2A	Absolute Y coordinate of end point of arc, line.
Y2I	Incremental Y coordinate of end point of arc, line.
YA	Current absolute cutter position in Y.
YC	Y coordinate of center of arc. Absolute or incremental depending on mode.
YCA	Absolute Y coordinate of center of arc.
YCI	Incremental Y coordinate of center of arc.
YI	Current incremental cutter position in Y.
Z	Current cutter position in Z. Absolute or incremental depending on mode.
ZA	Current absolute cutter position in Z.
ZI	Current incremental cutter position in Z.
