Generalization in UML Template

[Phil Roue]

If Class A is a generalization of both Class B and Class C, how can this be
represented in Visio?

Class B can be connected to Class A with a Generalization association, as
can Class C. However, this visually means Classes B and C are connected to
Class A with separate arrows. What I'd like is one arrow, one end connected
to Class A, but with multiple ends to connect to Classes B and C.

I could use an N-ary Link to connect Classes B and C to the arrow that goes
into Class A. But I am concerned that if I came to use Visio Enterprise
Architect, that code would not be properly generated from the N-ary Link.

I am using Visio 2003 Profession.

Thanks in advance for any suggestions.
