Modify Mesh Objects by Changing Properties

Mesh objects have additional properties that control the level of smoothness and creases. Crease properties of face, edge, and vertex subobjects are also reflected in the Properties palette.

• Level of Smoothness. Smooths or sharpens the edges of a mesh object.
  
• Crease Type. Specifies the presence of a crease (or sharpened edge) and the effect of smoothing. Smoothing does not affect a crease with a value of Always. A crease set to By Level retains its sharpness until the mesh object is smoothed to the specified crease level.
  
• Crease Level. When a crease is set to By Level, indicates the smoothing level at which the crease starts to lose its sharpness.
  

Modify 3D Subobject Properties

In addition to solids, surfaces, and meshes, you can also use the Properties palette to modify the properties of individual subobjects, such as faces, edges, and vertices. Different properties are available for different types of subobjects.

In some cases, the application of properties can differ depending on the object type. For example, you can modify the properties of mesh faces, including their color. However, the color appearance of a mesh face might differ from the equivalent color on a 3D solid face. This difference occurs because changing the color of a face modifies the diffuse color of the face, but not the ambient color (which is derived from the mesh material property). To obtain a closer match between the color of 3D solid and mesh faces, you can add lights and turn off the default lighting (which disables ambient lighting). You can also try assigning a material that has the same ambient and diffuse color.
