Schematic Diagram Templates and Examples

SmartDraw has all the schematic drawing templates and symbols you need as well as lots of other engineering diagrams.

How to Draw a Schematic Diagram

Step 1

Start with a Schematic Diagram Template

Start with a schematic diagram template that you can find in the Engineering category under New Document on your Dashboard.

Step 2

Add Your Power Source

Power and ground are the foundation of any schematic diagram. You'll start your schematic diagram by adding a symbol for your power source like a battery.

Step 3

Draw Circuit Lines

Next, start drawing circuits using the Line tool. Make sure you have the segmented or Shape Connector line type selected.

Step 4

Add Electrical Symbols

As you draw circuit lines, you can automatically add symbols at the end of a line from a pop-up menu of common symbols. This menu is intelligent and will populate with your most recently used symbols. Add resistors, logic gates, switches, and more.

Step 5

Drag and Drop Symbols

You can also drag and drop industry-standard electrical symbols to your circuit line. Your symbol will attach to the line seamlessly and SmartDraw will automatically rotate it to match the orientation of your circuit.

Step 6

Move Symbols

Move a symbol along a circuit line like a bead on a string. You can also detach the symbol by holding down the Alt key.

Step 7

Collaborate with Others

Invite team members to give you feedback and work on your schematic diagram in real-time. Make notes, design and troubleshoot as a group. SmartDraw is so easy to use, you can make changes in real-time.

Step 8

Print or Share Your Schematic Diagram

Once your schematic drawing is complete you can insert it directly to any Microsoft Office app like Microsoft Word® or PowerPoint®, or add it to Google Docs or Google Slides.

SmartDraw also has apps to integrate with Atlassian's Confluence and Jira. You can share your schematic diagram in Microsoft Teams. You can also easily export your schematic drawing as a PDF or print it.

What is a Schematic Diagram?

A schematic diagram uses industry standard electrical symbols to visualize a circuit. Engineers use schematic drawings to design circuits, understand how they work, and troubleshoot the logic in the case of problems.

Schematic diagram example

What is the Difference Between a Schematic and Pictorial Diagram

As the name suggests, a pictorial diagram uses pictures to represent components in a system. The key difference between a pictorial and a schematic diagram lies in standardization and abstraction. A pictorial diagram uses realistic images to represent the components in a system instead of abstract symbols. It's meant for a broader, less technical audience. In contrast, a schematic diagram uses a set of standardized electrical symbols to represent how components function and connect in a circuit. A pictorial diagram is great for beginners because the realistic images help with recognition and understanding. It's a great visual aid when teaching. Schematic diagrams are more useful for professionals who need to focus on function and flow to help with design and troubleshooting.

What is the Difference Between a Schematic and Wiring Diagram

A schematic diagram shows the logical flow in a circuit, while a wiring diagram visualizes the physical connections.

Engineers create schematic drawings to design and troubleshoot how a circuit should work. In contrast, a wiring diagram is used as a guide for installation or for troubleshooting the physical wiring by tracing it. Another way to say it is a schematic diagram is used to understand a circuit, while a wiring diagram is used to build it.
