When you start to draw in AutoCAD, you
will want to know how to specify
directions.
The standard User Coordinate System is
built off of the Cartesian Plane. The
Origin is the UCS shown in the picture.
This will always mark the 0,0 location ofthe drawing. The lines bound the first
quadrant.
By default, you indicate a horizontal
direction from left to right as zerodegrees. From bottom to top is ninety
degrees as shown in this figure.

When you need to specify
locations, you use theCartesian coordinate
systems, with X as the
horizontal axis and Y as the
vertical.
In a new file, the origin is
located in the lower leftcorner of the drawing,
denoted by the UCS icon.

As you draw in AutoCAD, youll
notice that the cursor changes
depending on your activity.
When AutoCAD is waiting for a
command, you see the standard
cursor.
When AutoCAD expects a point
location, youll see the point
selection cursor.
The point selection cursor is also
referred to as a pick box
If you need to select an object,
such as a line or circle, youll see
the object selection cursor.

Selection boxes can be initiated by
left clicking on a blank part of the
canvas.
A green square is a crossing
window and it will select any feature
that it touches.
The blue box is a bounding window
and will only select features that are
completely within the it.
Hold the left mouse button to draw a
lasso window to draw abstract
shapes and select features. Lasso
windows operate similarly to
bounding boxes in that it matterswhich direction they are drawn

Relative versus Absolute Cartesian Coordinate system:
Click the Customization icon in the lower left.
Check mark the Dynamic input tool.
When this tool is active, any object manipulation will be
in reference to the selected object or vertices.
When the tool is deactivated the absolute system is ineffect. This means that the actual AutoCAD coordinates
are used.
The @ symbol placed before typed coordinates will use
dynamic input.
The # symbol placed before typed coordinates will use
absolute input.

The Insertion Scale-Inserts content to the
selected unit.Engineers and Architects collaborate on
projects. Engineers might set the
insertion unit to feet, so when receiving
architectural drawings in inches the
conversion to feet is handled by
AutoCAD.
Similarly International collaboration
between Engineers may use a metric
conversion, so Engineering designs are
easily shared between groups.
Units for specifying the intensity of light
will be discussed if there is time to
discuss 3-D modeling.

Once youve set up the unit type, and the
Drafting Settings, you can set up the drawing
area. Use the Limits command (Limits ) to
set up the limits.The drawing limits are really just a guide to
help you visualize the area you are working
on and they do not actually limit you in any
way. You can draw outside the drawing limits,
but not by clicking.
It will only restrict the display of the grid if the
display grid beyond limits is unchecked
If you type Z A, your drawing view will
change to show the limits of your drawing.
Note that a grid behavior setting must be
turned on to limit the grids display to the
drawing limits.
Using limits and grid is a matter of preference
and drawing efficiency. If the product lends
itself to even measurements and right angles
then use grid and appropriately set snaps.
