Online Component Editor

Component Editor

Create custom components for Circuit Diagram using the new online Component Editor.

Choose a component template as a starting point, then you can:

  • View a preview of the component
  • Quickly find and locate any syntax errors
  • Compile component binary format online
  • Choose an icon for each configuration

The component compiler website should make designing custom components much easier. Once finished, you can always upload them for others to use here.

Today sees the launch of the newly designed website. As well as the redesign, we've added the new circuits page which allows you to share your circuit designs with other users of Circuit Diagram.

When you upload your circuit in Circuit Diagram's *.cddx format, a preview of your design will be automatically generated so that people can have a look at your circuit before they download it.

New site

Circuit Diagram 2.0 Beta 1 Released

This release includes a number of changes to make designing circuits easier, including automatic flipping of components when placing them and dragging from right to left or bottom to top. Documents can also be resized and there are many improvements to the use of keyboard shortcuts, including the ability to delete components by pressing the delete key on the keyboard.

Circuit Diagram 2.0 Alpha Released

A preview of Circuit Diagram 2.0 is now available to download. Please note that it is still in the development stage, and you may encounter problems using it.

Design Your Own Components

A completely redesigned system for components, which will now be loaded at runtime rather than being hard-coded into the application. They will no longer be written in code, but in XML, making it easy for anyone to write their own components to use in their diagrams.

This will enable the following features:
