How to drag blocks, label them, and format them. This animation is a simplified view. In the practice session coming up, you'll see many more shapes than you see here.
You begin creating a block diagram by dragging blocks to the drawing page and then labeling them. Label a block the same way as any other shape. Just select it and then type.
If you want to format text for the blocks (for example, to make the letters larger or smaller), you can select all the blocks and make your changes all at once.
