Altium MCAD CoDesigner 3.5.0: New Features and Enhancements Copy link

August 3, 2023
Copy link

The latest version of Altium MCAD CoDesigner is here! The 3.5.0 version of Altium MCAD CoDesigner brings several new features and enhancements, including:

New harness synchronization capability. This allows engineers to push the harness definition from ECAD to MCAD, where the mechanical engineer can define the cable routing through the enclosure and the connections to the printed circuit boards. The 3D harness definition can then be pushed back from MCAD to ECAD as part of the multi-board assembly. The physical length of wires, cables, and harness segments is assigned to the corresponding Harness entities in ECAD.

Multi-board assembly support for PTC Creo. This allows electrical and mechanical engineers to collaborate on the design of multi-board assemblies, including the synchronization of boards, mechanical enclosure, and 3D harness routing. 

Other enhancements. These include improved processing of component models, working with workspace folders, and support for the new versions of MCAD software.



We recommend diving deeper into the new features and improvements of MCAD CoDesigner 3.5.0 by exploring the complete release and details in the New Altium MCAD CoDesigner.

Altium has achieved CMMC Level 1 self-assessment, demonstrating our commitment to security. Users benefit from enhanced data protection, trusted relationships, access to SPRS scores, and CMMC 2.0 compliance. Organizations can leverage Altium 365 GovCloud to satisfy CMMC 2.0 requirements.

The SPRS score, the summary level score, helps identify a government contractor’s progress toward implementing the NIST SP 800-171 security controls.

We are actively working towards achieving Level 2 certification under CMMC 2.0. It is important to note that the CMMC Levels are cumulative, meaning that each level builds upon the requirements of the previous one..


For security and compliance information, visit our Trust Center. Altium 365 is designed to meet the requirements of defense and government projects. You can find the answer to your question and access the FAQ section by clicking here: My company works on defense or government projects. Can Altium 365 be used for such projects? Do you have corresponding certifications or compliance programs (NIST, ITAR, etc.)? Has your company achieved a Cybersecurity Maturity Model Certification (CMMC) of level 3 or higher?

Altium 365 PCB Compare Feature is Released Copy link

We are grateful to our beta testers for their valuable feedback. Your insights and suggestions have helped us significantly improve the product, and we couldn't have done it without you.

Specifically, your feedback helped us to:

  • The ability to reset the view by clicking outside of targeted objects.
  • The ability to show a legend that describes the colors representing the added/removed/modified objects visually and in different list icons.
  • The ability to filter the Differences list according to enabled layers:

The PCB Compare feature is valuable for PCB designers. It can be used to:

  • Save time and money by identifying design differences between versions before prototyping, uncovering potential problems early on, and avoiding costly iterations.
  • Help designers find differences between versions that are difficult to see with the naked eye.
  • Track changes and ensure design consistency with version comparison during development.
  • Pre-manufacturing verification to minimize production issues, ensuring a smoother manufacturing process.

Users can open the Project History or Releases page in the Altium 365 Web Viewer or Altium Designer to access the PCB Compare feature. From there, they can select two commits or releases to compare. Stay tuned for more updates and advancements as Altium continues to empower designers worldwide.

June 13, 2023
Copy link

When you open a Multi-board project from the main Projects page, you will find tabbed view options for schematic (MBS) and board assembly (MBA) views.


The Altium 365 Web Viewer interface provides universal access to Multi-board projects through a web browser, allowing you to perform standard operations like opening, sharing, and renaming. You can navigate through child projects, explore their content, and delve into the properties of MBS entities, including Modules and Connections.

Every subproject can now be individually opened, allowing you to understand their unique contributions to the overall design. The Multi-board Tasks and Releases views utilize the Multi-board's subprojects, facilitating effortless tracking and managing the progress. The History view showcases a timeline of major events that have occurred chronologically.
