Start the
Line
command and then type the coordinates of the fi rst point.
While
Dynamic Input
is on, specify the length of the line, press [Tab], and
then specify the angle. Do the same for the other line segments.
2.4 PRECISION METHOD 1: SNAP AND GRID
°
As you can see, the only method we used to precisely specify points in the
X,Y plane was to type the coordinates using
Dynamic Input
.
We do this because we cannot depend on the mouse to specify precise
points.
In order to use the mouse precisely, we have to use tools to control its
movement.
Snap
is the only tool in AutoCAD that can help us control the movement of
the mouse.
Using the
Status Bar
, click on the
Snap Mode
button.

Now, move to the
Graphical
Area
and watch the mouse jump to exact
points.
The
Grid
will show a grid of points on the screen similar to grid paper, which
is used in drawing diagrams (these points are not real points).
A
Grid
on its own is not accurate, but it is a helpful tool to use with
Snap
.
On the
Status Bar
, click on the
Grid
button.

You can now see the points displayed on the screen.
If you think the default values for either
Snap
or
Grid
do not satisfy your
needs, simply right-click one of the two buttons and the following shortcut
menu will appear:
