You can smooth the normals of a mesh to improve the appearance of the faceted triangle mesh. You can also use this option on imported files that contain triangles but do not contain normals, such as .stl, .dmt or .obj files.
To smooth the normals of a mesh:
- Import a triangle file that does not contain normals. The example shown below is a
.dmt file of part of a shoe sole:
The appearance is faceted:
- Select the mesh, and click Mesh Tools tab > Triangles panel > Smooth > Smooth Normals.
The Smooth Normals dialog is displayed where you specify the degree of smoothing required.
