NOTE (Dec 2, 2016): The upcoming release of Meshmixer 3.1 will decouple the app from 123D and feature several bug fixes. Please feel free to submit your bug reports and suggestions directly to We will continue working towards improving Meshmixer functionality.


Meshmixer is state-of-the-art software
for working with triangle meshes.

Do you need to clean up a 3D scan , do some 3D printing, or design an object that "fits" something else? Meshmixer can help. Think of it as a sort of "Swiss Army Knife" for 3D meshes.

Here are a few examples of how Meshmixer is being used today:
