Problem of creating a contraint

I try to create a contraint in a class diagram for an association by clicking the ‘Contraint’ tool in the tool menu, moving the mouse pointer to the association and drawing, however, nothing happens. It seems that the tool for creating contraints doesn’t work. I am using the latext enterprise version. Tks.

Hi user,

Sorry for my late response. In order to create “Constraint”, you need to have 2 associations first. Please refer to the flash movie about how to create Constraint between associations:

If there is any further inquiry, please do not hesitate to ask.
