CAD is an abbreviation for
computer aided design.
This is computer software
used to create, design,
develop, and manipulate
architectural drawings.
This method has quickly
become the industry
standard versus traditional
drafting for creating
drawings.

There are many advantages to
using CAD over traditional
drafting.
1. Easy manipulation of the
drawing after its initial
creation
2. A smoother and quicker
process for editing drawings.
With traditional drafting, you
would have to erase, re-draw
or possibly start over with a
drawing.

The drawing elements within
a CAD environment can easily
be altered, edited, resized ,
and moved.
Example - if a window or
door was misplaced or
needed to be relocated
before construction, you can
open a CAD drawing and shift
it to the correct location.

Some basic CAD commands
consist of the following:
 Move
 Erase/Delete
 Cut/Trim
 Copy
 Rotate/Turn
 Scale
Copyright © Texas Education Agency, 2012. All rights reserved.
These commands are used to
manipulate the elements
within the drawing file.
Drawings are all about
communication. So, if a
drawing is incorrect or
unclear, it has to be fixed in
order to properly
communicate.

One potential drawback of
CAD files is organization.
Since a CAD file is really a
computer file in a digital
environment, you have to be
careful how you file, store,
organize, and distribute these
types of files.
With one stroke of a button,
you could easily lose hours or
days worth of work from a
computer.
Copyright © Texas Education Agency, 2012. All rights reserved.
Within a CAD file, we also
want to organize the drawing
elements for easier usage.
There are commands and
tools within CAD software that
help organize and coordinate
drawings.
This can be just as important
for drawing files as being
able to create drawing
elements.

Today, we want to focus on
correcting a CAD drawing
that has some errors.
We will use a CAD program in
order to manipulate the
drawing.

Let’s apply your new
knowledge and work on
your own CAD files.
