When working with maps
that include 3D data such as raster-based surfaces, you will often
want to display different views in 3D so that you explore, examine,
and analyze the surface from different perspectives.
Use any of the following
options to view your 3D map interactively:
- Switch to 3D view—Displays
the 3D Navigation toolbar, which contains the commands you need
to change the 3D view (for example 3D Orbit) and turns on display
driver acceleration to enhance 3D performance.
- 3D Zoom—Simulates
the effect of a camera's zoom lens by making objects appear closer
or farther away.
- 3D Pan—Changes
the view to match where you move the cursor.
- Constrained Orbit —Moves
the surface map around a target.
panning with a camera in the direction that you drag.
- Walk or Fly—Simulates
walking or flying through a 3D model.
- Motion Path Animation—Records
and plays back a walk-through or fly-through of a model to visually
demonstrate a surface map.
- Other AutoCAD commands—Allow you to view
and navigate in 3D. For example, you can use the VISUALSTYLES to
hide or show lines and shade 3D data or Camera to
place a camera so that you can manipulate and save 3D perspective
For more information
about the above commands, refer to the AutoCAD Help.
improve the display of a surface after zooming in, use the Resample
option. This resamples / requeries the data so
it is as clear as possible, getting rid of things like pixelation.
