Program code
GEOAX(1, a)
Several channel axes can become geometry axes on a transformation change.
Example:
Channel axes 4, 5 and 6 become the geometry axes of a 5axis transformation. The geometry
axes are thus all substituted before the transformation. The current frames are changed when
the transformation is activated. The axial frame components of the channel axes which become
geometry axes are taken into account when calculating the new WCS. Rotations programmed
before the transformation are retained. The old WCS is restored when the transformation is
deactivated. The most common application will be that the geometry axes do not change before
and after the transformation and that the frames are to stay as they were before the
transformation.
