**How to enter the coordinates in CAD and detailed examples**

**The ways to enter coordinates xy in AutoCAD** (the way to enter coordinates in cad, enter coordinates of points in cad):

Drawing commands remind us to enter coordinates of points into drawing. In 2-dimensions drawing (2D), you only enter abscissa (X) and ordinale (Y). In 3-dimensions drawing (3D), you have to add altitude (Z).

For example: When you use line command, the prompt lines will appears:

**Specify first point**: Enter coordinates of the first point**Specify next point or [Undo]**: Enter coordinates of the end point

**Using the left mouse button to choose (PICK)**: Combine with methods of catching point.

**Absolute coordinates:** enter absolute coordinates X, Y of the point following to origin of coordinates (0,0) as below:

**Command: Line↵****Specify first point: -50,-50↵****Specify next point or [Undo]: 30,-50↵**

**Polar coordinates**: Enter polar coordinates of the point (D<α) following to distance D between the point with origin of coordinates (0,0) and oblique α in comparison with standard line.

Relative coordinates: Enter coordinates of the point following to the defined last point on drawing. At the prompt line, you enter @X,Y. [email protected] means ( Last Point) – the defined last point on drawing.

**Command: Line↵****Specify first point: 30,-50↵****Specify next point or [Undo]: @0,100↵**

**Relative polar coordinates:** At the prompt line, you enter @D<α, in which:

- D: Distance between the point needs to define with the last point on drawing.
- α angle is the angle between standard line with straight line segment of 2 points.
- Standard line is the line starting from origin of relative coordinates, lies on positive direction of X axis.
- Positive angle is counter-clockwise one. Minus angle is clockwise one.
- For example: In the picture, we used defined point A and syntax @10<30

**Direct distance entry**: Enter relative distance in comparison with the last point, orient by Cursor and press Enter.

**Good luck!**
