Hello All,

I am trying to replicate a kinematic simulation in Unreal engine which I have done in NX using Blueprints, if anybody has done this previously, please guide me or give some insights?

Has anyone here worked on a similar project—transferring or re-creating kinematic mechanisms from CAD environments (like NX, SolidWorks, etc.) into Unreal?

Any guidance, best practices, or examples would be greatly appreciated. Specifically, I’m interested in:

- Handling joint constraints or linkages

- Managing motion sequences

- Maintaining mechanical accuracy within Unreal’s physics/animation system

If you’ve done something similar or know of resources/tutorials that could help, I’d be grateful for your insights.

Thank you in advance!

See [Using Datasmith with Solidworks in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community](https://dev.epicgames.com/documentation/en-us/unreal-engine/using-datasmith-with-solidworks-in-unreal-engine)

There is not Assembly Relations after importing.

currently I am trying with exporting the kinematics and simulation data from NX as a .json file building a blueprint to read that data to replicate the animation positions, any reference material on this approach available?
