How to smooth out regions on meshes.

NoteTo better see the smoothing effect, first shade your mesh by using Diagnostic Shading or WindowDisplay > Hardware Shade . Increasing the mesh Transparency (in the Control Panel) will also help.

1. Choose Mesh > Mesh Cleanup > Mesh Smooth .
2. Select the mesh to smooth.
3. To smooth the entire mesh, go to step 6.
4. Click down with the to place points that will define the region to smooth. At least three points are required to create a region.
   NoteTo modify the position of a point, click and drag it. To add a new point anywhere, click on the line between any two points.
   NoteThe view must be maintained to complete the region. If the view is modified, the polyline region disappears.

   

5. Press the Select button.

   The selected triangles are highlighted in blue.

6. Press the Smooth button repeatedly until the desired amount of smoothness is achieved.

   The mesh updates after each iteration.

   

   NoteTo keep the vertices from moving by more than a certain amount, turn Restrict on, and use the Maximum Permitted option.
7. To see a color deviation map showing the deviation between the original and smoothed mesh, turn on Show Deviation Map and adjust the Deviation Map Settings if necessary.

   The color map display updates each time you click the Smooth button.

8. Use Edit > Undo to undo successive smoothing iterations.

   The color map display updates for each smoothing step that you undo.
