About Element References
It is helpful to consider some terminology:
Elements - the objects we add to the model.
When we add elements, we may need to select other elements that are already in the model - we call them the Reference Elements.
Reference-elements - those elements that may need to be in the model before we can add a new element.
To delete an element, ...
If you want to delete a Reference-element you may also delete those elements that can only exist with the Reference-element.
A pop-up warning will list those elements that you will also delete in addition to the Reference-Element.
Thus, it may be useful to review the relationships before you delete an element.
It is also possible that you cannot delete an element before you delete a Reference-element.

Example 1: Reference-Elements of a CAD-Line: Its reference-elements are simple - there is a Point at each end of the CAD-Line •Point22 and Point25. Note: The derived-name of the Point with the lower-number (Point22) is the start-Point of the CAD-Line The derived-name of the Point with the higher-number (Point25) is the end-Point of the CAD-Line |

Example 2: Reference-Elements of a 2D-Cam Its reference-elements are: •those elements that in the model before you can add the 2D-Cam (a Profile and a Part ( which is also defined by its start-Point and end-Point at the end of its CAD-Line). and Reference-Elements are: •those elements that you may add to the model, and need the 2D-Cam to exist in the model ( e.g.: we may add a Polyline to the 2D-Cam) |
