The 'Show Vertex Normals' command displays small lines that represent the vertex normal facing directions for each vertex in a Vertex Normal map. Split lines represent creased hard edges, where single lines represent smoothed edges. Users must have a vertex map present to see anything using this commnd. Users can create a map based on the objects current smoothing using the 'Set Vertex Normals' command. The resulting map will appear in the vertex map lists viewport.
