Drawing connectors
When you choose a connector from the toolbar, the mouse pointer changes to 
. As you move the cursor over an object you can see the available connection (glue) points. To connect two shapes move the mouse cursor over a gluepoint, click on it with the left mouse button to establish the first point, and then drag the mouse cursor (left button still pressed) to the other gluepoint and release the mouse button. The ends of the line are now docked and the connection is established (see Figure 10).

You can also place the beginning or the end of a connector to the middle of an object. This is useful when the final position of the object is not yet fixed. When you move the object Draw will automatically select the optimal location for the connector ends (see Figure 11).

As with all other objects, connectors have one or more control points to simplify the construction of the drawing. You can use these points to change the shape, length and proportions of the connector line (see Figure 12).

To remove a connector from an object, either move the end of the connector from the glue point of the object or simply delete the connector entirely.
