How Do I Draw a Linear Dimension in AutoCAD?

Are you struggling to draw linear dimensions in AutoCAD? Don’t worry, we’ve got you covered!

In this tutorial, we will guide you step-by-step on how to draw accurate linear dimensions in AutoCAD. So, let’s get started!

Step 1: Open AutoCAD and Start a New Drawing

First, open AutoCAD and start a new drawing. You can either click on the New Drawing button or use the keyboard shortcut Ctrl+N.

Step 2: Draw the Objects to be Dimensioned

Next, draw the objects that you want to dimension. This could be lines, circles, rectangles, or any other geometry that requires measurement. Make sure that your drawing is clean and organized.

Step 3: Activate the Dimension Tool

To dimension an object in AutoCAD, you need to activate the Dimension tool. There are several ways to do this:

  • Option 1: Go to the Annotate tab in the Ribbon. In the Dimensions panel, click on Linear.
  • Option 2: Type “DIMLINEAR” in the command line and press Enter.
  • Option 3: Use the keyboard shortcut “D” followed by “I” (press D then I).

Step 4: Select Objects to Dimension

After activating the Dimension tool, AutoCAD will prompt you to select objects to dimension. Click on one end of an object and then click on its opposite end. Repeat this process for all objects that require dimensions.

Step 5: Positioning Dimensions

Once you have selected the objects, AutoCAD will place the dimensions on your drawing. By default, the dimensions are placed above the objects. However, you can easily change their position.

To move a dimension, simply click on it and drag it to the desired location. You can also use the grips that appear at the ends of each dimension line to adjust its length or angle.

Step 6: Customize Dimension Settings

If you want to customize the appearance and behavior of your dimensions, you can do so by accessing the Dimension Style Manager. To open this manager, go to the Annotate tab in the Ribbon and click on Dimension Style.

Within the Dimension Style Manager, you can modify various properties such as text height, arrow size, extension lines, and units. Take some time to explore these options and adjust them according to your requirements.

Step 7: Save Your Drawing

Finally, don’t forget to save your drawing! Click on the Save button or use the keyboard shortcut Ctrl+S. Give your file a name and choose a location on your computer where you want to save it.

Congratulations! You have successfully learned how to draw linear dimensions in AutoCAD. With this skill, you’ll be able to create accurate drawings that communicate measurements effectively.
