How Do I Create a Mass in Sketchup?

Creating a Mass in Sketchup

Sketchup is a powerful 3D modeling software that allows you to create detailed models and bring your designs to life. One of the key features of Sketchup is the ability to create masses, which are large volumes that represent buildings, structures, or objects in your model. In this tutorial, we will explore how you can create a mass in Sketchup and use it to enhance your designs.

Step 1: Open Sketchup

Before we begin creating a mass, make sure you have Sketchup installed on your computer. Open the software and start a new project by clicking on “File” in the top menu bar and selecting “New”.

Step 2: Set Up Your Workspace

Once you have started a new project, it’s important to set up your workspace for creating a mass. Go to the “View” menu and select “Toolbars”.

Make sure the “Large Tool Set” option is checked. This will give you access to all the tools needed for creating a mass.

Step 3: Draw Your Base Shape

To create a mass, you first need to draw its base shape. This can be done using various tools such as the Line tool, Rectangle tool, or Circle tool. Select the appropriate tool from the toolbar and start drawing your base shape on the ground plane.


  • Use guides: To ensure accuracy and precision, consider using guides while drawing your base shape. Guides can be created by clicking on the ruler at the edges of your workspace and dragging them onto your desired location.
  • Snap to inferencing points: Sketchup has an inferencing system that helps you snap to specific points or lines while drawing. This can be extremely useful when creating complex base shapes for your mass.

Step 4: Extrude Your Base Shape

Once you have drawn your base shape, it’s time to extrude it and give it volume. Select the Push/Pull tool from the toolbar and click on your base shape. Drag the cursor upwards to extrude the shape and create a volume.


  • Use measurements: If you need precise dimensions for your mass, enter the desired height in the Measurements box at the bottom right corner of the Sketchup window while using the Push/Pull tool.
  • Create complex shapes: To create more complex masses, consider using multiple base shapes and combining them using Sketchup’s powerful editing tools like Intersect Faces or Boolean operations.

Step 5: Refine Your Mass

After extruding your base shape, you can refine your mass by adding more detail or making adjustments. Sketchup offers a wide range of tools for editing your model, such as the Move tool, Rotate tool, or Scale tool. Experiment with these tools to achieve the desired look for your mass.


  • Add textures: To make your mass look more realistic, consider applying textures to its surfaces. Sketchup allows you to import textures or apply preloaded materials from its library.
  • Create components: If you plan to reuse your mass in other projects or need to duplicate it within the same project, consider creating a component. This will allow you to easily edit all instances of the component simultaneously.

Step 6: Save Your Project

Once you are satisfied with your mass, it’s important to save your project. Go to the “File” menu and select “Save” or “Save As” to save your work. Choose a location on your computer and give your project a descriptive name.

Creating a mass in Sketchup is a great way to add depth and realism to your models. By following these steps and using the various tools and techniques available in Sketchup, you can create impressive masses that will enhance your designs. So go ahead, start experimenting with masses in Sketchup, and let your creativity soar!
