The following is from the UML 1.4.2 specification <snip> 5.43.3 Presentation Options ... Various options are possible for showing the navigation arrows on a diagram. These can vary from time to time by user request or from diagram to diagram. • Presentation option 1: Show all arrows. The absence of an arrow indicates navigation is not supported. • Presentation option 2: Suppress all arrows. No inference can be drawn about navigation. This is similar to any situation in which information is suppressed from a view. • Presentation option 3: Suppress arrows for associations with navigability in both directions, show arrows only for associations with one-way navigability. In this case, the two-way navigability cannot be distinguished from no-way navigation; however, the latter case is normally rare or nonexistent </snip>
AroUML currently only supports presentation option 3 There is a issue already raised to request the other options here - http://argouml.tigris.org/issues/show_bug.cgi?id=535 If you add your vote to that issue then you'll raise its profile in the eyes of the developers, You will find it difficult to draw an association with no navigability in ArgoUML. You can only draw unidirectional or bidirectional you will then have to edit the navigable association ends to turn off navigability. If you want to draw non-navigable by default you should create a new issue for this.
