In this recipe, we'll improve the surface of a model by working with its mesh. Meshmixer was designed to provide a modeling interface that frees the user from working directly with the geometry of the mesh. In most cases, the intent of the program succeeds, but in some cases, it's good to see how the underlying mesh works.
We'll use some brush tools to make one of our models better, thereby taking a look at how this affects the mesh structure.
We'll need the toy block that we scanned with 123D Catch.
We will proceed as follows:
