How Do I Change the Thickness of Insulation in AutoCAD?

Changing the thickness of insulation in AutoCAD can be done easily using a few simple steps. In this tutorial, we will guide you through the process, explaining each step along the way.

Step 1: Open the Drawing

To begin, open the AutoCAD drawing that contains the insulation you want to modify. You can either choose an existing drawing or create a new one.

Step 2: Select the Insulation

Next, select the insulation object that you want to change the thickness of. You can do this by using the “Select” tool from the toolbar or by typing “SELECT” in the command line and then selecting the object.

Step 3: Accessing Properties

Once you have selected the insulation object, right-click on it to open a context menu. From this menu, select “Properties” to access the properties panel.

Step 4: Modifying Thickness

In the properties panel, locate and click on the field that corresponds to “Thickness.” This field may vary depending on how your drawing is set up, but it is usually labeled clearly as “Thickness.”

Note: If you cannot find a field specifically labeled as “Thickness,” look for any field related to dimensions or size that could affect the insulation thickness.

Step 5: Inputting New Thickness

Once you have clicked on the field for “Thickness,” you can input a new value. AutoCAD generally uses units such as inches or millimeters for measurements, so ensure that your input matches your desired unit of measurement.


  • If you are unsure about what thickness value to use, consult the project specifications or discuss it with the relevant professionals.
  • Remember to consider any insulation standards or regulations that may be in place for your project.
  • Double-check your input to avoid errors and ensure accuracy.

After inputting the new thickness value, press “Enter” or click outside of the field to apply the changes. The insulation object will now reflect the updated thickness.

Note: It is important to review your drawing after making changes to ensure that all dimensions and annotations are still accurate and properly represent your design intent.


In this tutorial, we have shown you how to change the thickness of insulation in AutoCAD. By following these steps, you can easily modify the thickness value and update your drawing accordingly.

Remember to consider any project requirements and standards when changing insulation thickness. With this newfound knowledge, you can confidently make adjustments to your AutoCAD drawings.
