Enhancing a Block Diagram

Block Diagram for Systems In this Tutorial we complete the Block Diagram created in the last tutorial by enhancing it’s appearance.  As mentioned in the last tutorial, a block diagram is simple to make and very versatile to use which is one reason why it is such a popular drawing type in Visio. In the scientific world a block diagram is often used to represent a portion of a larger diagram. This could be a function diagram, a circuit diagram, an hydraulic, pneumatic or other engineering diagram – in each case the block diagram allows the user to focus on one specific detail of the parent diagram.

A Block Diagram as a high level flowchart

In many cases, and particularly in electronics, a block diagram is used as a top level flowchart. A block diagram can be used to describe whole circuits by breaking them down into smaller sections (or blocks). The blocks represent a particular function and with the aid of connector lines, the block diagram illustrates the relationship between them and shows how they connect.

Tip: There is normally no detail shown within this kind of block diagram at component level as the blocks are simply there to show how the inputs and outputs interact at each stage


[br]As these diagrams are representative of electronics systems they are often called block systems diagrams. However, for our tutorial we stay with the conference plan we created in the last tutorial and make some modifications to it.

Enhancements to our Block Diagram

In this block diagram tutorial we cover a number of intermediate Visio techniques, including:

  •  adding shadows
  • offsetting shadows
  • Adding and formatting shape fills
  • numbering shapes in sequence
  • adding door and window shapes from another stencil
  • formatting architectural shapes
  • adding signage to the block diagram
