How Do I Show a Section Cut in SketchUp?

Are you struggling with showing a section cut in SketchUp? Don’t worry, we’ve got you covered!

In this tutorial, we’ll walk you through the step-by-step process of displaying a section cut in SketchUp. So, let’s dive right in!

Step 1: Creating a Section Plane

To show a section cut, we first need to create a section plane. A section plane is an imaginary cutting plane that allows us to see inside our model. To create a section plane, follow these simple steps:

  1. Select the Section Plane tool: Look for the “Section Plane” tool in the toolbar or simply press “P” on your keyboard to activate it.
  2. Position the section plane: Click on any surface or line where you want the section cut to be placed. You can move it around later if needed.
  3. Adjust the size of the section plane: Use the blue handles to resize and rotate the section plane according to your requirements.

Note: You can also use the “Move” and “Rotate” tools to reposition and adjust the orientation of the section plane after creating it.

Step 2: Activating Section Cut

Now that we have our section plane in place, let’s activate the section cut feature to make it visible within our model:

  1. Select the Section Cut Face tool: Locate and click on the “Section Cut Face” tool from your toolbar.
  2. Select your section plane: Click on your previously created section plane. This will generate a face representing the cut portion of your model.

Note: By default, the section cut face will have a solid color. However, you can customize its appearance by applying materials or textures.

Step 3: Adjusting Section Cut Display Settings

If you want to further enhance the visibility and appearance of your section cut, SketchUp provides various display settings that you can tweak according to your preference:

  • Section Fill: Control the transparency and color of the section cut face by adjusting the “Section Fill” settings in the “Styles” panel.
  • Section Plane Visibility: Toggle the visibility of the section plane itself using the “Section Planes” checkbox in the “View” menu.
  • Section Cut Visibility: Hide or show the section cut face using the “Hide Section Cuts” checkbox in the “View” menu.

Note: You can also access these settings by right-clicking on your section plane and selecting “Entity Info.”

Step 4: Updating Your Model

If you make any changes to your model after creating a section cut, it’s important to update it so that the section representation remains accurate. To update your model, follow these steps:

  1. Select your section plane: Click on your existing section plane (the blue selection highlight will appear).
  2. Right-click and choose “Update Section Plane”: This will refresh the section cut based on any modifications made to your model.

Note: The “Update Section Plane” option is only available when you have an active selection of the section plane.


Congratulations! You’ve successfully learned how to show a section cut in SketchUp.

By creating a section plane, activating the section cut face, adjusting display settings, and updating your model when necessary, you can effectively showcase the internal details of your design. Make sure to experiment with different styles and settings to achieve the desired visual effect. Happy modeling!
