Meaning
Determine tool length components from the current tool
orientation
Determine tool length components from the orientation
of the active frame
Determine tool orientation of an active frame on selec‐
tion of tool, tool points in Z direction
Determine tool orientation of an active frame on selec‐
tion of tool, tool points in Y direction
