What is a Block Diagram and How to Make One

A block diagram is a specialized flowchart used in engineering to visualize a system at a high level. SmartDraw helps you make block diagrams easily with built-in automation and block diagram templates. As you add shapes, they will connect and remain connected even if you need to move or delete items.

Create your block diagram to identify the most important components of your system so you can focus on rapidly pointing out potential trouble spots.

A block diagram is especially useful for visualizing the inputs and outputs of your system, while what happens inbetween can remain in a black box.
