Connecting Lines to Shapes
Most software diagrams involve connecting one or more shapes to each other using lines.
To connect two shapes, click on Connect Shapes in the SmartPanel. Your mouse will become a pencil. Touch one end of the pencil to the shape you're trying to connect and without letting go of the mouse drag the line to the edge of the other shape. When you see the anchor symbol, you can let go of the line and it will attach to the object.
By default the connecting line will be a segmented line, but you can choose a straight line, an arc, or something else from the the Line Shape drop-down menu on the SmartPanel.
