With dynamic viewing, you can display the effects of changing your viewpoint as you
make the changes. Using this method, you can also simplify your view temporarily by
choosing only the objects that you need to determine the view. Alternatively, if you
press Enter without selecting any objects, 3D Dynamic View displays a model of a small
house instead of your actual drawing. You can use this house to define the viewing
angle and distance. When your adjustments are complete and you exit the command, the
changes are applied to the entire 3D model in the current view.

Set Clipping Planes

You can clip the views of your drawing by positioning front and back clipping planes
that control the visibility of objects based on their distance from a theoretical
camera. You can move the clipping planes perpendicular to the line of sight between
the camera and target (where the camera is pointing). Clipping removes the display
of objects from the front and back of clipping planes. The following illustration
shows how clipping planes work:

You can also set clipping planes when you create a camera glyph. For more information,
