Query Drawing (aftermath)

[Toshilap]

Another stupid question.
I had all tables added to Diagram pane and executed my query and it all went splendidly well.
I had made screen print and tried to do this again.
So I pasted my query into SQL pane-executed it BUT diagram pane will not show me all the tables that were involved.
So if I need this view Diagram-SQl-Result I have to recreate it every time by adding tables and joining them again? Entering SQL ststement does not automatically creates Diagram, does it?
Thanks

I finally got it all together and forgot where I put it.
