【Select】: Select the data to be deleted. 
【Set as Default】: Set the offset data as the default offset.  
【Default】: The data is the default current base coordinate offset. 
【Cancel】: Cancel the selection.

Example: 
When expressed in coordinate system {A}: 
B is (207,0,112,180,0,0), D
AC
 = 1000mm, if user want to set the world reference 
coordinate system to {C}, just express the position and orientation of user 
coordinate system {C} in coordinate system {A}. 
As figure shown, the offset of the base coordinate system should be 
(1000,0,0,0,0,180). 
Former TCP coordinates of B (207,0,112,180,0,0) in base coordinate system, after 
user coordinate system offset setting: 
Becomes: B ’(793,0,112,180,0,180)
