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

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

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.

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
