Current Procedure ORIGIN UCS

Each procedure has its own UCS, which is fully specified in GPP2, as the ORIGIN UCS. The ORIGIN UCS is defined relative to REF, both in terms of position, and in terms of orientation.

The following system variables describe the procedure Origin UCS:

System Variable	Meaning
X_ORIGIN Y_ORIGIN Z_ORIGIN	X, Y and Z or the ORIGIN UCS zero point, expressed in the REF coordinate system.
I_ORIGIN J_ORIGIN K_ORIGIN	Orientation of the ORIGIN UCS Z vector, expressed in the REF coordinate system.
IX_ORIG JX_ORIG KX_ORIG	Orientation of the ORIGIN UCS X vector, expressed in the REF coordinate system.

The orientation of the Y unit vector can be obtained from a vector multiplication of the Z and X vectors (Z * X).

The following diagram shows the REF UCS and an ORIGIN UCS. It shows the ORIGIN zero point, Z axis and X axis, all expressed in the REF coordinate system.
