The Location / Orientation page of the Create New and Edit/View Detailed Source… dialogs two functions.
The Location Parent Coordinate System should not be confused with the Logical Parent Node in the Tree View though they are often chosen to be the same. The Location Parent Coordinate System should also not be confused with the Reference Coordinate System for a particular location or orientation transformation. The Location Parent Coordinate System will default to the Logical Parent Node but it can be changed to any other coordinate system in the FRED document. All of the nodes listed in the Geometry and Source sections of the Tree View represent available coordinate systems in the FRED document.
The Reference Coordinate System for the first location and orientation action will default to the Location Parent Coordinate System. For subsequent location and orientation actions, Reference Coordinate System will revert to the Reference Coordinate System on the previous action, i.e. the line above.
NOTE: The source or object is placed at the origin of the Location Parent Coordinate System. From there, the source or object can be moved using the Location/Orientation dialog or this tab of the Detailed Source Dialog.
This feature can be accessed in the following ways: •Right mouse click on a source node in the object tree and select Position / Orientation from the list menu •In a Detailed Source dialog, select the Location / Orientation tab
