OO Class Diagrams
I'm doing some modeling using Object-Oriented Class Diagrams. The first OO Class Diagram I created uses the correct symbology for Associations, Aggregations, and Compositions. Every Class Diagram I have created since that first one uses incorrect symbology; it looks more like Barker notation for Conceptual Data Models rather than OO Class Diagram notation. I attached two files to depict the problem. The "Correct.JPG" file shows the symbology on my original Class Diagram. The "Incorrect.JPG" shows the symbology on subsequent class diagrams. In this example, I literally a cut and pasted the graphics from the original Class diagram to a new Class diagram. Is there a way to fix this problem?
