Hi Peter,

The UMLE00080 error message means that before one can diagram the
collaboration between two roles, there should be a relationship between the
two classes from which those roles are based.

To resolve this, you can create a binary association between the classes in
the static structure diagram which has the classes, and set the association
role in your collaboration diagram to the binary association which created
in the static structure diagram.

You can refer to the following steps to model collaborations in Visio:

1) On a static structure diagram, draw two classes and connect both classes
with a binary association.
2) In the Model explorer(Navigator), right-click a Package \ New \
Collaboration diagram.
3) Draw two Classifier Roles and connect them with an association role.
4) Double-click the classifier roles and set their classifiers to the
classes from the static structure diagram.
5) Double-click the association role and set it to the binary association
from the static structure diagram.

By the way, for the issue about software modeling, I suggest you can post
it in a more appropriate newsgroup, you'd get better and quicker help there:

microsoft.public.visio.software.modeling

Thanks for your understanding!

Best regards,
