Optimize your 3D models

For best rendering and best possible real-time performance, your 3D models need to be converted and might need to be optimized before using Microsoft Dynamics 365 Import Tool (Preview). Third-party applications that convert CAD files often have tools that can optimize content as well.

The following table lists software tools that you can use to convert and/or optimize your CAD files or intermediate files and export them as a supported file format. Your use of third-party applications is subject to terms between you and the third party. Microsoft does not endorse any particular third-party application and assumes no responsibility or liability for any third-party application you elect to use.

Important

Dynamics 365 Guides uses meters as the default scale unit. If your 3D model scale is set to millimeters when you export from your CAD solution, the model will be converted to meters in Dynamics 365 Guides. For example, if your model is 50 millimeters, it will be converted to 50 meters. To ensure size consistency between your CAD solution and Dynamics 365 Guides, make sure to set your model scale unit to meters when you export.


Here are examples of CAD, converted, and optimized 3D models.

Performance targets

The Dynamics 365 mixed-reality applications can be used on Microsoft HoloLens, immersive headsets, and mobile devices. The goal is to provide the highest possible visual fidelity without adversely affecting performance.

The following table lists some general conservative targets to aim for when acquiring or authoring 3D models for a range of hardware. When in doubt, target the midrange profile for a balance of fidelity and performance.
