"Go" Visio drawing use case Model diagram There is no include relationship

Transferred from: http://blog.csdn.net/shuixin536/article/details/8289746

Since Rose was not installed on the computer, I decided to use Visio to draw the use-case model diagram in UML, but when I drew it, I found that there was no arrow that indicated the include relationship between use cases and use cases. I started thinking that I was not familiar with Visio, so I looked it up, didn't find it, asked colleagues, they rarely use Visio, the Web, the original Visio does not have this feature, do not know why Microsoft to remove this relationship.
No way, only think of other ways to find an opportunistic approach:

1. Use an arrow to draw the relationship first. For example, use extend arrows.

2. Double-click the drawn extend arrow to change its name to <<include>> in the popup dialog box.

Remember, there are 3 steps, don't stop the second step.
