Choose Preset 3D Views
You can select predefined standard orthographic and isometric views by name
or description.
A quick way to set a view is to choose one of the predefined 3D views. You
can select predefined standard orthographic and isometric views by name or
description. These views represent commonly used options: Top, Bottom,
Front, Left, Right, and Back. In addition, you can set views from isometric
options: SW (southwest) Isometric, SE (southeast) Isometric, NE (northeast)
Isometric, and NW (northwest) Isometric.
To understand how the isometric views work, imagine you are looking down
at the top of a box. If you move toward the lower-left corner of the box, you
are viewing the box from the SW Isometric View. If you move toward the
upper-right corner of the box, you are viewing it from NE Isometric View.
Define a 3D View with Coordinate Values or Angles
You can define a viewing direction by entering the coordinate values of a
point or the measures of two angles of rotation.
This point represents your position in 3D space as you view the model while
looking toward the origin (0,0,0). Viewpoint coordinate values are relative to
the world coordinate system unless you change the WORLDVIEW system
variable. The conventions for defining standard views differ between
architectural (AEC) and mechanical design. In AEC design, the perpendicular
view of the XY plane is the top or plan view; in mechanical design, the
perpendicular view of the XY plane is the front view.
The following illustration shows a view defined by two angles relative to the
X axis and the XY plane of the WCS.
