Accessing, Defining & Managing System Preferences

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.


Your Altium NEXUS software provides a central location from where you can set up various preferences across different functional areas. These are global system settings that apply across projects and relevant documents.

Configuration of preferences is performed from within the Preferences dialog, accessed by clicking on the  control at the top-right of the main design window.

The Preferences dialog provides a number of useful tools to ensure your set of preferences is just as you require, including:

  • Ability to import preferences defined in a previous instance, or version of the software.
  • Ability to save preferences to, and load preferences from, a Preferences file (*.DXPPrf).
  • Ability to set the options and controls on the active preferences page, or all pages, back to their defaults.

If you have a Workspace, you can formally release your Altium Design Preferences into a target Item (and revision thereof) in that Workspace. Once the preferences set has been released, the preferences can be reused across installations of the software.

When connected to a Workspace, a green icon ( ) appears next to Data Management Preferences pages that are subject to the Workspace's control.

Preferences are clustered into categories. Click on an entry within a category on the left-hand side of the dialog to present the detailed page for that area on the right. Use the controls and options available on a loaded page to configure your preferences for that area of the software as required. This could be a mixture of satisfying company policy and your preferred working environment. More information about the various pages of preferences can be found below.
