How to convert 3DM to USDZ
- 1Add your 3DM fileDrop the .3dm file into the box, or pick it from disk. Multiple files are converted one after another.
- 2Pick USDZ as the outputUSDZ is already selected on this page. Adjust scale, up axis or triangle budget if the target application is picky.
- 3Download the resultThe .usdz file is written locally and appears as a download button next to your file.
About 3DM
3DM is the openNURBS based native format of Rhino. It stores NURBS surfaces, meshes, layers, blocks and object attributes, and the openNURBS toolkit makes it one of the few native CAD formats that is genuinely readable outside its host application.
- Rhino
- Grasshopper
- Revit via plug-in
- Blender via add-on
About USDZ

Questions
Is this 3DM to USDZ converter free?
Yes. There is no account, no daily quota and no watermark. The tool is a static web page and the work is done by your own CPU, so there are no server costs to pass on.
Are my files uploaded anywhere?
No. MeshFormat loads a WebAssembly build of the geometry kernels into your browser and reads the file locally. You can open the network tab and confirm that nothing leaves the page, or disconnect after the page has loaded and keep converting.
How large can a 3DM file be?
The practical limit is your available memory rather than an arbitrary cap. Models up to a few hundred megabytes work on a normal laptop; very dense scans convert faster if you lower the triangle budget in the options.
What is lost when converting 3DM to USDZ?
Vertex colors: vertex colours are dropped because the output format has nowhere to store a colour per vertex.
Which programs open USDZ files?
Reality Composer, Safari, Maya, Houdini and most other tools that work with 3D meshes read .usdz directly.
