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: PinSwapper Commands

The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to interactively perform part-swapping (between sub-parts of a component) within the design workspace. A part is swappable with another part when both parts belong to the same Part Group. It is common for a component to consist of multiple functionally equivalent subparts. Part swapping allows the nets of such equivalent sub-parts to be swapped.

For a high-level overview of swapping functionality in Altium NEXUS, see Pin, Pair and Part Swapping.


This command is accessed from the PCB Editor by choosing the Tools » Pin/Part Swapping » Interactive Part Swapping command from the main menus.


After launching the command, everything in the PCB workspace is masked (faded), except those parts that are swappable. Keep an eye on the Status Bar, it will prompt you for the next action, to choose the first sub-part to swap. After clicking on any pin in the swappable sub-part, you will be prompted to choose a different sub-part from ABC, where ABC is the designator of the component you are swapping parts in. Click on a pin in the target sub-part to complete the swap action.

Pins will be swapped between the source and target sub-parts in accordance with the defined Part Sequence settings, if no part sequence is defined they will be allocated in a random fashion.


  1. Part swapping for a component is configured with the part group and sequence ID attributes. The part group indicates which sub-parts are able to be swapped with one another. The sequence ID attribute determines equivalence of the pins between swappable sub-parts. These are both text attributes and are accessible in the Part tab of the Configure Pin Swapping dialog.
  2. Part swap information will also appear in the Messages panel.
  3. Design changes that are a result of you performing a sub-part swap in the PCB editor are propagated back to the schematic using the standard Design Update process (run the Design » Update Schematics command from the PCB Editor).
