Re-topologize

Tools for making modifications to existing mesh faces are contained in the Re-topologize fly-out menu.

Re-triangulate

To refine the proportions of the mesh faces without changing the surface topology of the model you can apply the Re-triangulate tool. The tool will activate only when portions of the mesh have been selected.

Sub-divide Selection

The Sub-divide tool refines the existing mesh by adding additional faces to improve detail in areas of transition. This tool is only available when geometry has been already selected.

Decimate Mesh

The Decimate Mesh tool can be used to change the number of faces in the mesh based on a selection or for the entire model. The dialog displays the number of faces that are selected and will change as the percentage of decimation is changed. Initially you will be able to use Decimate all to change then entire model but this will change to Decimate selection once if select a portion of the model.
