AutoCAD 2022 – Dimensions

Learn about the Dimensions Commands in AutoCAD 2022, how to use it? By Akash Periyasamy Last updated : April 01, 2023

What is Dimensions?

Dimensions are elements that are added to the object in the design workspace to specify the geometric values of the object. It includes length, breadth, width, angle, etc. All these values are necessary for the production of the component as dimensions play an important role in the assembly. Dimensions ensure that the component is made as per the required size without much alteration.

How to Enable Dimensions Command?

The two standard methods of enabling the dimension command are explained below:

  1. First Method:
    In this method, the command is enabled by clicking on the icon shown below which is present in the ribbon panel.
    AutoCAD Dimensions (step 1)
  2. Second Method:
    It is an alternative method in which the command is enabled by typing DIM in command line.

Types of Dimensions

The different types of dimensions are,

AutoCAD Dimensions (step 2)
  • Linear
  • Aligned
  • Angular
  • Arc Length
  • Radius
  • Diameter
  • Jogged
  • Ordinate

Now, let us understand each type of dimension with a suitable example for better understanding.

1) Linear Dimension

  • Draw a line of random length in the design workspace.
    AutoCAD Dimensions (step 3)
  • Enable the linear dimension command.
    AutoCAD Dimensions (step 4)
  • Click on the first point on the line.
    AutoCAD Dimensions (step 5)
  • Again, click the second point of the line.
    AutoCAD Dimensions (step 6)
  • Now, the dimension of the line will be displayed.
    AutoCAD Dimensions (step 7)

2) Aligned Dimension

  • Draw an inclined line of random length in the design workspace.
    AutoCAD Dimensions (step 8)
  • Enable the aligned dimension command.
    AutoCAD Dimensions (step 9)
  • Click on the first point on the line.
    AutoCAD Dimensions (step 10)
  • Again, click the second point of the line.
    AutoCAD Dimensions (step 11)
  • Now, the dimension of the line will be displayed.
    AutoCAD Dimensions (step 12)

3) Angular Dimension

  • Draw two lines in such a way that they are inclined to each other.
    AutoCAD Dimensions (step 13)
  • Enable the angular dimension command.
    AutoCAD Dimensions (step 14)
  • Click on the first line.
    AutoCAD Dimensions (step 15)
  • Again, click the second line.
    AutoCAD Dimensions (step 16)
  • Now, the dimension of the line will be displayed.
    AutoCAD Dimensions (step 17)

4) Arc Length

  • Draw an arc joining two lines as per your wish for good understanding.
    AutoCAD Dimensions (step 18)
  • Enable the Arc Length Command.
    AutoCAD Dimensions (step 19)
  • Click on the arc to determine its length.
    AutoCAD Dimensions (step 20)
  • Now, the length of the arc is determined.
    AutoCAD Dimensions (step 21)

5) Radius Dimension

  • Draw a circle of random dimension.
    AutoCAD Dimensions (step 22)
  • Enable the radius dimension command.
    AutoCAD Dimensions (step 23)
  • Click on the circle for which the dimension is to be determined.
    AutoCAD Dimensions (step 24)
  • Now, the radial dimension of the circle is determined.
    AutoCAD Dimensions (step 25)

6) Diameter Dimension

  • Draw a circle of random dimension.
    AutoCAD Dimensions (step 26)
  • Enable the diameter dimension command.
    AutoCAD Dimensions (step 27)
  • Click on the circle for which the dimension is to be determined.
    AutoCAD Dimensions (step 28)
  • Now, the diametral dimension of the circle is determined.
    AutoCAD Dimensions (step 29)
