Hierarchical diagram lines connecting off center

I am trying to make hierarchical diagrams. I’ve never had this issue before but the lines are connecting off center.

What do I need to change?

The magnets settings for the shapes:

  • For more insight, switch on View > Magnets
  • For more control, select the shapes and choose Edit > Magnets > Positions

(Experiment, for example, with zero magnets, or two magnets)

For understanding.

No, they are connecting to the absolute centre (you are expecting the lines to connect to the centre of each side). The absolute centre is the default Magnet, that is, when you do no t have Magnets set for the Shape, but connection from Lines is allowed.

Learn about Magnets, and set them on each Shape to suit your particular need. Draft8 has provided details.
