Whether produced on computer or paper, most 3D design relies on 2D
representations for accurate description of objects and their positioning. Maps,
plans, cross-sections, and elevations are all examples of 2D representations.
Each of these views represents an orthographic view. In familiar terms, you
might think of these views as "flat" or "straight-on," or as "looking at right
angles."
Orthographic views are two-dimensional, each defined by two world coordinate
axes. Combinations of these axes produce three pairs of orthographic views:
top and bottom; front and back; left and right.
Orthographic views are a special case of
axonometric views on page 7722 . You
can set viewports to the various orthographic views using the
viewport
right-click menu
on page 7370 or keyboard shortcuts on page 7645 .
Out-of-Range Types
When you specify values and keys for a controller, you are defining animation
over a range of time. You choose Out-of-Range Types to determine how the
animation continues outside a specified range. Out-of-Range choices include
holding a constant value, and various ways of repeating the animated range.
The easiest way to work with Out-of-Range Types is in the Track View Function
Curve mode.
