When you’re looking to connect two objects together, such as compatible diagrams, there are three types of connector lines to choose from: straight, angled (elbowed), and curved. Your connector line will appear as blue circles as your cursor moves around the screen.
To Draw a Connector:
1) Select the Connectors graphic from your AutoShapes toolbar.
2) Select Connectors and choose your connecting line.
3) Click on what you want to attach.
4) Drag cursor to the object you wish to attach to.

Feel free to move objects around, remembering that objects that are unlocked will appear as green circles and connected objects will appear as red circles.
