Learn how to make a block diagram with some of the engineering examples of the 101 Diagramss that we have provided in the following images below. A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks.
Observe the following samples of the diagram to see more detailed components of a block diagram.

Block diagrams are heavily used in engineering in hardware design, electronic design, software design, and process flow diagrams. These diagrams are typically used for higher level, less detailed descriptions that are intended to clarify overall concepts without concern for the details of implementation. Its structure provides a high-level overview of major system components, key process participants, and important working relationships.


A block diagram is focused on the input and output of a system. It uses boxes and circles. When you are about to make one, you will create blocks that represent important points of interest in the system from input to output. Lines connecting the blocks will show the relationship between these components. The principal parts and functions are represented by blocks connected by straight and segmented lines illustrating relationships.


In making a block diagram, feel free to add as little or as much detail as you want using more specific symbols. The best way to understand block diagrams is to look at those examples of block diagrams that we have above. Click on any of these block diagrams included and you would know more about the diagram.
