When I want to delete the connection of 'D' key generattion.

[syseo]

In the tutorial of the manual, the meeting point of Tracter and Crane is connected with each other by using 'D' key. And then the line is red (or pink?).
When I want to disconnect the red line, any key can't make it disconnected?

What is the method to disconnect it?

Help me.

Have you checked the general Flexsim tutorial about Keyboard Interaction?

D connects and E disconnects. On a US keyboard those are the keys that are up and below each other.
