LINES TO MAKE USING AUTO CAD CORNER coordinates to Cartesian By BUDI Maryanto

One way to make a line to draw with AUTO CAD program is to use Cartesian coordinates angle . Cartesian angle is the angle formed by the horizontal and perpendicular lines
where for a formula in AUTO CAD is
line image = ( X , Y )
where X = is the point coordinates for the X axis ( in this case , usually horizontal )
                Y = is the point coordinates for Y axis ( in this case , generally perpendicular lines )

By providing value Cartesian coordinates of the axis angle X and Y axis , so that will form a line , if these lines will form a plug in the wake of geometric , such as squares, triangles , and others.
It is as fundamental in AUTO CAD drawing using Cartesian coordinates of the corner .
One advantage of using the Cartesian coordinates of a corner in the form of line drawings making will be faster , when compared with using the polar angle .
This is caused in the command line corner Cartesian coordinates shorter , just enter the value of the X axis and Y axis values ​​, which are separated by commas .

as an example
When we will draw the shape to a square box with four sides is 100 units ( in this case could mean centi- meter unit , or milli meters or other unit of length )
Then the way is :
1 . In the command window type the line , then place the cross hair on AUTO CAD drawing work area , then press enter
2 . Put the value 0 on the X axis and 0 on the Y axis , ie, by typing at the command prompt 0.0 Specify next point or [ Undo ] :
This means that we have determined the point 0 on both axes will be made in the first point to make the line
3 . Put a value of 100 on the X axis and 0 on the Y axis , ie, by typing at the command prompt 100,0 Specify next point or [ Undo ] :
This means we will make a horizontal line to the right with a length of 100
4 . Put the value 0 on the X axis , and 100 on the Y axis , ie, with 0,100 on the command prompt type the Specify next point or [ Undo ] :
This means we will make a straight line k bear up with a length of 100
5 . Put the value of -100 on the X axis and 0 on the Y axis , ie, by typing at the command prompt ---- 100,0 Specify next point or [ Undo ] :
This means we will make a horizontal line to the left , with a length of 100
6 . Put the value 0 on the X axis , and - 100 on the Y axis , ie, by typing
0 , -100 at the command prompt Specify next point or [ Undo ] :
This means we will make a perpendicular line down the length of 100
