Diagram and connection functions

If you look here on the bottom left you will see some symbols residing under the Diagram, these symbols are used when you connect a diagram. You rely only need to use the two left most.  The erase cross, the cursor arrow,  the straight line and the lying down Z shape.

These are used to create connections on a new diagram, show how the flow is to be carried out. The closest analogy I can think of is a train travelling down a track. Here and there we have exchange points but most is a fairly straight track.

On the right hand side you have one box with the 100% indicated, that is the Diagram zoom factor. The box show here with the Default.dgr gives you the name of the presently used diagram.
