Polygon Reduction
Reduces the number of vertices of a mesh by a specified ratio while preserving the mesh's shape to the extent possible.
After importing a high-polygon mesh from a 3D scanner or other source, reducing the number of vertices can make for a more manageable file size and data that is easier to edit.
Can be used in Face Selection Mode.

Usage
Polygon reduction can be applied to one or more polygon meshes.
- Select Tools > Modify Mesh > Polygon Reduction.
- In the Toolbox, select Modify > Mesh > Polygon Reduction.
- Specifying a value for Rate in the of the Tool Parameters will draw a preview of the result in the Figure Window.
- Click Apply to apply polygon reduction.
Tool Parameters
- Rate
- Specifies the ratio of vertices used for polygon reduction.
- Drag the slider to preview the results in real time.
- Selection Only Checkbox
- When selected, polygon reduction is applied to the selected vertices only.
