New in CoDesigner

Altium's MCAD CoDesigner technology connects the mechanical and electrical design domains, allowing the mechanical and electronic engineers to pass the loaded PCB back and forth between the two domains.

In your Altium design software, this is achieved through an extension that loads and extracts board and component data from the PCB editor, the MCAD CoDesigner extension. In the MCAD software the Altium CoDesigner Add-in performs the same function, loading and extracting board and component data from the MCAD software.

The ECAD and the MCAD software pass design changes through an Altium Workspace, which can be hosted in the cloud on Altium 365, or on your company network using an Altium On-Prem Enterprise Server. The Workspace acts as a bridge, with both the ECAD and MCAD software connecting to it. The Workspace holds the board and component data, allowing the ECAD and MCAD engineers to continue to work autonomously, Pulling and Pushing their changes when they are ready.

  • The updates are listed in reverse order on this page - you'll find the latest updates at the top of the page.

  • The videos on this page demonstrate CoDesigner features using Altium Designer. The process of CoDesigning between other Altium design clients and your MCAD software is essentially the same.

  • For the latest announcements and engaging conversation, head on over to the MCAD CoDesigner forum.

  • Refer to the note in the right-hand pane for information on which features will be available in your installation of MCAD CoDesigner.

Supported Versions

CoDesigner is under continuous development, this page outlines the changes made in each version. Because the CoDesigner extension and Add-ins can be updated separately from the update cycle of your Altium design software, this page also includes information about supported versions of Altium software, as well as the supported versions of MCAD software.

Download and install the version of the Add-in you require for your MCAD software from the MCAD CoDesigner Plugins section on the Altium Downloads page.


New in CoDesigner 3.14.0

Released: 17 December 2025 – Version 3.14.0

Feature Highlights

Automatic Harness Push when you Save to Server

When you perform a Push from ECAD in the CoDesigner panel, you are not pushing the ECAD project to the Altium Workspace, you are pushing a special ECAD-to-MCAD data package. For a harness project this package includes: the connectors, splices, connectivity ("from-to" data), and harness topology.

Saving the ECAD project to the Workspace is performed independently from a Push to MCAD. This separation of MCAD Pushing and Saving to Server can be a source of confusion, where an ECAD engineer might think that the Save to Server they performed at the end of the day meant that everyone else who needs access to that design data, is now up-to-date and ready-to-go.

To simplify the process of keeping files in sync, the first time the harness project is Pulled from the Workspace into MCAD, that project is flagged as an MCAD CoDesigner project. From then on, whenever the project is Saved to Server in ECAD, it is also automatically Pushed to the Workspace, ready to be Pulled into MCAD. Auto-Push removes the burden of remembering to perform a manual CoDesigner Push after each save in ECAD. When the MCAD engineer performs a Pull, they are alerted if the last MCAD Push was automatic. 

An MCAD auto-push is now performed automatically when the project is Saved to the Server.An MCAD auto-push is now performed automatically when the project is Saved to the Server.

  • The Workspace performs automatic Pushing, initiating this process after the first Pull into MCAD has been performed.

  • Automatic Pushing has been enabled for Altium 365 Workspaces. Support for On-Prem Enterprise Server Workspaces will be added soon.

If an automatic Push cannot be performed, the MCAD engineer is warned that the version of data they are pulling is not the latest ().

Automatic Pushing is not performed when:

  • The ECAD project has only been saved to the working folder – the project is yet to be Saved to the Server. Once a Save to Server has been performed, automatic Pushing is available.

  • The ECAD project has failed CoDesigner's validation checks – these must be resolved before an automatic or manual MCAD Push can be performed.

  • There are multiple PCB files in the ECAD project, which have all been Saved to the Server – this can be resolved by the ECAD engineer performing a manual MCAD Push on the correct PCB.

  • CoDesigner 3.3 is the latest version available for Altium NEXUS Client.

  • CoDesigner 2.10 is the latest version available for Altium CircuitMaker.

This update has been tested on the following MCAD platforms and Add-in versions:

MCAD Version MCAD Add-In Version
Autodesk Fusion® (Note 1) 3.14.0.2
Autodesk Inventor Professional® - version 2024 3.14.0.2
Autodesk Inventor Professional® - versions 2025, 2026 3.14.0.2

Notes:

  1. Altium CircuitMaker only supports Autodesk Fusion.

  2. Siemens NX is only available to designers as part of an Altium Enterprise Solution. From MCAD CoDesigner 3.8 onwards, there are multiple versions of the installer for MCAD CoDesigner for Siemens NX, to suit different versions of the Siemens NX software. These installers all install identical versions of MCAD CoDesigner, they differ only in their detection of the currently installed version of Siemens NX. For MCAD CoDesigner 3.7 and older there is a single installer, and after installation of MCAD CoDesigner Siemens NX may show a warning when launched that the difference between the current version and the signed version is too great. This warning can be ignored, your installation of MCAD CoDesigner will function correctly. Alternatively, the Show Warning when Loading option in the Customer Defaults dialog in Siemens NX, can be disabled ().
