I am attempting to import a model developed in Autodesk Inventor 2025 into the Simscape Multibody environment within MATLAB/Simulink for physics-based multibody simulation. However, the standard procedure recommended by MathWorks involves using the Simscape Multibody Link plugin, which exports the model geometry and topology to an XML file (Physical Modeling XML format) compatible with Simscape.
The issue is that the current version of Simscape Multibody Link officially supports only Inventor 2021 and earlier, which prevents its direct use with Inventor 2025.
Therefore, I am seeking a viable alternative to export or convert the Inventor 2025 model to a format compatible with Simscape Multibody, without relying on the Simscape Multibody Link plugin.

Hey,
I understand that you intend to import a model from Autodesk Inventor 2025 to Simscape Multibody environment. As you correctly noted that the current version of Simscape Multibody Link Plugin support Autodesk Inventor versions (2009 to 2021), as attested by the following documentation from MathWorks:
https://www.mathworks.com/help/sm/ug/installing-and-linking-simmechanics-link-software.html
The obvious workaround is to use an earlier version of Autodesk Inventor, which is compatible with the plugin.
If you do not intend to use an older version, then you can export your assembly from Inventor 2025 as a neutral CAD file, e.g. STEP(.stp), and then import it into Simscape Multibody using the built-in CAD import workflow. Please note that this method brings in geometry and inertia properties, but you must manually re-establish kinematic relationships (joins and constraints).
If you have many parts or repeated joint types, you can script the Solid-block creation and parameter settings in MATLAB to speed things up.
Additionally, keep an eye on the MathWorks Add-On Explorer, MathWorks may release the latest update of the Link Plugin soon.
