The SysML Use Case diagram displays elements and relations that describe services provided by a system. It also depicts various stakeholders (such as users or system operators) that consume services. In the Bank_SysML.ump example project from the C:\Users\<username>\Documents\Altova\UModel2022\UModelExamples directory, the following are examples of services:
•A bank customer interacts with an ATM to withdraw cash
•A bank employee performs ATM maintenance
•A bank employee refills the ATM
