Viewing Surfaces in 3D
When working with maps that include 3D data such as raster-based surfaces,
display different views in 3D to 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.
■ Swivel—Simulates 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 views.
For more information about the above commands, refer to the AutoCAD Help.
