Adding a frame box to a diagram
You can add a frame box to the diagram; the box has no semantic meaning and ignores any overlap with any other symbols. You generally use frame boxes to visually convey grouping.
To add a frame box:
1. On the diagram tab, click the Frame Box button.
2. On the diagram click where you want to add the frame box.
3. Position and Resize the frame box as required.
* 
If you move the frame box, the diagram items contained in it do not move with the frame box.
You can display an image in a Frame Box and ensure that the Frame Box is shown in the background.
