Connecting objects with lines
You can connect any two objects with the Line tool (
). Note that the line tool may change its appearance to resemble the style of line it is currently set to create.
Click the Line tool.
Click the first object you would like to connect. This object becomes the "source" of the line.
Click the second object you would like to connect. This object becomes the "destination" of the line.
Once objects are connected by a line, they stay connected no matter how much you change them or move them around. That means the logical integrity of your diagram is preserved regardless of how you choose to style it. You can disconnect a line from an object by dragging one of its endpoints.
