Use the Allow Multiple Plot States 
  
 tool to display the deformed model shape with the undeformed model
  shape superimposed. Set the render style for both images to wireframe, and
  toggle off the translucency of the superimposed plot from the
  Superimpose Plot Options dialog box. Rotate the view to
  obtain a plot similar to that shown in 
  Figure 1.
  By default, the deformed shape is plotted for the last increment. (For clarity,
  the edges of the undeformed shape are plotted using a dashed style.)
