DisplayShaded + Boundaries + Hidden Lines
The Shaded View Boundaries and Hidden Lines command displays the objects in the model as a colored, shaded rendering. Visible surface boundaries are shown as continuous lines. Surface boundaries that are hidden from view by other surfaces in the model (hidden lines) are also shown. The line type for the hidden lines should be changed to "dashed" by selecting the Dashed hidden line mode check box in the Graphics category in the System Options tab of Options/Properties dialog box.
