I have a question about sequence diagrams.
When building sequence diagrams,
Is it enough to make one diagram for each user case?
or we need to draw a set of sequence diagrams for each instance of a user case. (represents a sequence of actions performed by a system that gives the observed result of a value to a particular actor of use)

Remember that sequence diagrams represent possible interaction scenarios. Therefore, for each relevant scenario, you must draw a different sequence diagram. The meaning of "relevant" is up to you. This can be only one if you think that for a specific use case there is only one corresponding scenario (perhaps other scenarios are obvious and not worth a specific diagram) or many
