Exploring Drafting
Animated models are useful in the architectural
fi eld. For example, an architectural project can
be presented with an animated tour through a
building for a design proposal.
One of the more advanced applications
of CAD technology is the use of computer-
generated animation and imaging for special
effects in fi lms. Computer drawing and animation
programs are also used for applications in the
medical fi eld. While originally conceived for
engineering purposes, CAD-based graphics
are now used in a variety of industries. Career
opportunities in CAD drafting and design will
continue to expand as the technology develops.
rendering in this manner is known as a scene.
When the scene is rendered, material fi nishes
and other effects are calculated based on the
lighting used. Computer rendering programs
require greater amounts of resources in order to
perform the calculations needed. The original
model may be created within the program, or
it may be imported from a different modeling
program with less powerful rendering capability.
Some modeling and rendering programs
allow you to animate models so that they can
be shown in actual operation. Models created
in this manner are assigned movement
parameters for frame-by-frame animations.

lighting and materials.
