The name of an Operation is colored light green when viewed in the Operation Navigator (ONT) , as seen below. What does this mean?
The color of the Operation name will be changed to the color green whenever it is placed in the Unused Items folder in either the Program , Machine Tool , Geometry or Method View in the ONT . Moving these operations out of Unused Items will cause the name to be displayed correctly. Posting an Operation that is in the Unused Items group can cause errors. Notice in the picture below that the FACE_MILLING_MANUAL operation is colored green.
Now notice that the Operation name is now displayed as the color black after moving.
The Operation color will be the same in all of the ONT views.
