How Do I Fill a Section Cut in SketchUp?

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

In this tutorial, we will walk you through the step-by-step process of filling a section cut in SketchUp. So, let’s dive in and get started!

Step 1: Creating a Section Cut

Before we can fill a section cut, we need to create one. To do this, follow these simple steps:

  1. Select the Section Plane Tool: Look for the ‘Section Plane’ tool in the toolbar or navigate to ‘Tools’ > ‘Section Plane’.
  2. Place the Section Plane: Click on any desired point in your model to place the section plane. You can move it around or resize it later if needed.
  3. Adjust the Orientation: Use the blue handles to adjust the orientation of the section plane until you are satisfied with its position relative to your model.

Step 2: Activating Section Cut Fill

Now that we have our section cut ready, let’s proceed with adding fill to it:

  1. Select the Paint Bucket Tool: Locate and select the ‘Paint Bucket’ tool from your toolbar or access it by going to ‘Tools’ > ‘Paint Bucket’.
  2. Select a Material: In SketchUp, materials are used for applying textures and colors. Click on any desired material in the Materials panel or create a new material by clicking on the ‘+’ icon.
  3. Filling the Section Cut: With your desired material selected, click inside the area enclosed by the section cut. The fill will automatically be applied to the section cut.
  4. Adjusting the Fill: If needed, you can adjust the scale, position, or other properties of the fill material by right-clicking on the section cut and selecting ‘Texture’ > ‘Position’, ‘Scale’, or other relevant options.

Step 3: Fine-tuning the Section Cut Fill

In some cases, you may want to make additional adjustments to ensure that the section cut fill looks just right. Here are a few tips:

  • Changing Material: If you’re not happy with the selected material, simply select a new material from the Materials panel and apply it to the section cut as described in Step 2.
  • Editing Material Properties: To modify properties like color, texture, or transparency of a material, right-click on the material in the Materials panel and select ‘Edit’.
  • Hiding Section Cut Edges: If you want to hide the edges of your section cut for a cleaner appearance, right-click on your section plane and choose ‘Entity Info’. In the Entity Info dialog box, uncheck ‘Section Slice’ under ‘Tags’.


Filling a section cut in SketchUp is a simple process that can greatly enhance your model’s visual appeal. By following these steps and making any necessary adjustments, you’ll be able to create stunning section cuts with beautiful fills. So go ahead and give it a try!
