PRIVACY
Your 3D files are opened and processed on your device. Mes3D does not upload your models. The app collects app usage and diagnostic data to improve Mes3D, as described in the Privacy Policy.
GOOD TO KNOW
- Mes3D displays models as meshes. Animations, advanced materials and complex scene hierarchies may not appear in full for every format.
- Measurements and analysis depend on the units and quality of the source file. Print weight is an estimate that assumes 100% infill.
- Available in 35 languages, with a language setting inside the app.
