StarUML Instructions for Use—Use Case Diagram, Sequence Diagram, Activity Diagram

Installation and inspection

Install StarUML first. StarUML-5.0-with-cm.rar

First check whether the Model Explorer video on the right side of the interface is displayed;

If it is not displayed, click on the top menu》view》Model Explorer to display it;

Create a use case diagram:

Set the color: Tools>Options: white background\black line\black text

Just drag the Actor out from the left side and double-click the graphic to rename it; Use Case is a use case, just drag it out and write the function points of your own service.

How to draw a direct connecting line: select the line that has been drawn, ctrl+L;

Other note components: text, note;

Create a timing diagram:
