How Do You Enter Coordinates in AutoCAD?

by

In AutoCAD, entering coordinates is an essential skill that allows you to precisely position objects in your drawings. Whether you are designing a building plan, creating a mechanical part, or drafting a landscape, knowing how to input coordinates accurately will greatly enhance your productivity and accuracy.

Using Cartesian Coordinates

Cartesian coordinates are the most common method used in AutoCAD to specify points and objects. These coordinates consist of an X, Y, and (sometimes) Z value that define the location of a point in three-dimensional space.

To enter Cartesian coordinates in AutoCAD, follow these steps:

  1. Launch the Command Line: To start entering coordinates, click on the Command Line at the bottom of the AutoCAD window or press Ctrl + 9 on your keyboard.
  2. Type the Command: Begin by typing the command that requires coordinate input. For example, if you want to draw a line, type “LINE” and press Enter.
  3. Enter the Coordinates: After typing the command, AutoCAD will prompt you to enter the first point. Here’s where you can enter your coordinates:
    • Type Absolute Coordinates: If you know the exact X, Y (and Z) values for your point relative to the origin (0,0), simply type them separated by a comma.

      For example: “3.5,2.75” or “10,-4”.

    • Type Relative Coordinates: If you want to specify a point relative to another known point instead of using absolute values, start with @ before each coordinate value. For example: “@3,@-1” means moving 3 units horizontally and 1 unit vertically from the previous point.
  4. Continue or End: After entering the first point, AutoCAD will ask for additional points if required by the command. Press Enter to finish entering coordinates and complete the command.

Using Polar Coordinates

Polar coordinates are an alternative method used in AutoCAD to specify points. These coordinates consist of a distance and an angle from a reference point, typically defined as the origin (0,0).

To enter polar coordinates in AutoCAD, follow these steps:

  1. Launch the Command Line: Just like with Cartesian coordinates, start by opening the Command Line.
  2. Type the Command: Type the command that requires coordinate input. For instance, if you want to draw a circle, type “CIRCLE” and press Enter.
  3. Enter the Coordinates: AutoCAD will prompt you to enter the center point of your circle. Here’s how you can enter polar coordinates:
    • Type Absolute Polar Coordinates: To specify a distance and an angle directly from the origin, use @distance
    • Type Relative Polar Coordinates: If you want to specify a point relative to another known point using polar values, start with @ before each coordinate value. For example: “@1<90" means moving 1 unit at a right angle (90 degrees) from the previous point.
  4. Complete or Continue: After entering the center point of your object, AutoCAD may ask for additional information or points, depending on the command.

With these two methods, you can confidently enter coordinates in AutoCAD and accurately position objects within your drawings. By mastering this skill, you’ll gain greater control over your designs and improve your overall drafting efficiency.
