You can change a view
without interrupting your current operation using a feature that
combines panning and zooming.
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.
NoteMore powerful options
for dynamic viewing in 3D are available in the 3DORBIT command.

Set Clipping Planes
You can create cutaway, or section, 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:
NoteYou can also set
clipping planes when you create a camera glyph. For more information,
see
Change Camera Properties.
To set clipping planes
(DVIEW)
- At the Command prompt, enter dview.
- Select the objects on which to base the
view.
- At the Command prompt, enter cl (Clip).
- Enter f to set a front
clipping plane or b to set a back clipping plane,
or press Enter.
- Position the clipping plane by dragging
the slider or entering a distance from the target.
- Press Enter to exit the command.
NoteYou can also set
clipping planes when you create a camera glyph. For more information,
see
Change Camera Properties.
