First: this is the wrong sub forum, this section is for developers to discuss the code and documentation.

Do you really want to rotate a pdf? LibreCAD doesn't open or import a pdf. Maybe you meant a dxf.
If so, what do you mean with the red cross? Is it part of the file/drawing or the 0,0 coordinate marker of LibreCAD?
In the first case you should activate Snap Intersection in the snaps toolbar at the bottom of the screen.
In the second case you can activate Snap on Grid or type 0,0 in the command line to specify the rotating center.
