Set the display mode for a model

Do one of the following:

• From the main menu, select Display and choose Flat Lighting or Wireframe. (When either of these modes is not selected, the default display is Smooth Shade). Alternately, you can press the W key to display in wireframe mode.
  NoteWireframe display mode can increase the time to refresh the 3D View during interactive operations (sculpt, track, dolly, tumble, and so on) as the subdivision level on the model is increased.
• Right-click in an empty area of the 3D View and select Flat Lighting or Wireframe from the menu that appears.
