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 (with Altium Designer Enterprise Subscription) and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Parent page: PCB Commands

The following pre-packaged resources, derived from this base command, are available:

Applied Parameters: None


This command is used to cross probe from a chosen object on the current PCB document to its corresponding counterpart on the relevant source schematic document. Cross-probing is a powerful searching tool to help locate objects in other editors by selecting the object in the current editor. Between the PCB and Schematic Editors, full cross-probing support is provided for documents, components, buses, nets, and pins/pads(s).


This command can be accessed from the PCB Editor by:

  • Choosing the Tools » Cross Probe command from the main menus.
  • Clicking the  button on the PCB Standard toolbar.


There are two cross-probing modes available:

  • Continuous Mode – this mode allows you to remain in the source document while cross-probing to different objects on the target document. Position the cursor over the required object within the workspace then click or press Enter. The corresponding object will be highlighted on the target document. Continue cross-probing further objects or right-click or press Esc to exit.
For this mode, it is more efficient to have the PCB (source) and schematic (target) documents open side-by-side in the main design window.
  • Jump To Mode – this mode allows cross-probing to a single object (i.e. 'single-shot cross-probing'), making the target document the active document. Position the cursor over the required object within the workspace then Ctrl+click or press Ctrl+Enter. The corresponding object will be highlighted on the target document with that document becoming the active document.


  1. When using the command repeatedly in Continuous Mode, the last object chosen will be the one displayed/highlighted. Cross-probe filtering is not cumulative.
  2. The cross-probed objects on the target document will be displayed in accordance with the Highlight Methods defined on the System - Navigation page of the Preferences dialog. Highlighting will not be applied to the originating document.

Applied Parameters: Action=ToggleFastCrossSelect


This feature facilitates dynamic, bi-directional object cross-selection. It is used to select corresponding objects between PCB and schematic documents. In other words, when you select an object on the PCB document, the same object on the source schematic document is also selected (and vice-versa).


This feature is accessed from the PCB editor in one of the following ways:

  • Click the Tools » Cross Select Mode command from the main menus.
  • Enable the Cross Selection option in the Cross Select Mode region of the System - Navigation page of the Preferences dialog.
  • Click Shift+Ctrl+X.


With this feature enabled, click to select one or more objects within the workspace. Those same objects will become selected on the corresponding document.

The target document will not be made the active document. It is therefore a good idea to have both source and target documents open side-by-side.


  1. Cross Select Mode display behavior is controlled using the Cross Select Mode controls on the System - Navigation page of the Preferences dialog.
  2. If a document is closed then reopened, the project must be re-compiled before the feature will work correctly for affected objects on that document.
  3. When enabled, the icon for the feature on the main Tools menu will become highlighted.
