How Do You Make a Solid Model in SketchUp?

Creating a solid model in SketchUp is essential for building accurate and detailed 3D designs. Whether you are an architect, interior designer, or hobbyist, mastering this skill will greatly enhance your ability to bring your ideas to life.

In this tutorial, we will explore the step-by-step process of creating a solid model in SketchUp. So, let’s dive in!

Step 1: Understanding Solid Modeling

Before we begin, let’s clarify what solid modeling entails. In SketchUp, a solid is a three-dimensional shape that has volume and mass.

It is composed of surfaces that enclose a region of space. Solid models are crucial for 3D printing, accurate measurements, and realistic rendering.

Step 2: Starting a New Project

To create a solid model in SketchUp, open the application and start a new project by selecting “File” from the top menu bar and clicking on “New”. Alternatively, you can use the shortcut Ctrl+N (Command+N for Mac users).

Step 2.1: Choosing the Template

A template provides predefined settings for your project such as units of measurement and visual styles. Select an appropriate template from the dialog box based on your requirements.

Step 3: Drawing Your Design

In this step, we’ll start creating our solid model by drawing the desired shapes using SketchUp’s drawing tools. These tools include:

  • Pencil Tool: Use this tool to draw freehand lines or curves.
  • Line Tool: Create straight lines by clicking at the desired starting point and then clicking at the endpoint.
  • Rectangle Tool: Draw rectangles by specifying the starting point and dimensions.
  • Circle Tool: Create circles by specifying the center point and radius.

Combine these tools to draw the basic outline of your model. Don’t worry about precision at this stage; you can refine it later.

Step 4: Push/Pull to Create Volume

Now that you have drawn the outlines, it’s time to give them depth and turn them into solid objects. The Push/Pull tool is perfect for this purpose.

Select the surface or shape you want to extrude, then click on the Push/Pull tool. Click on the surface and drag it along the desired direction to create volume. Repeat this process for each surface that needs thickness.

Step 5: Grouping and Solidifying

To ensure your model is a solid object, you need to group its individual components together. To do this:

  1. Select all the surfaces that constitute your solid model by either dragging a selection box around them or holding down Shift while clicking each one separately.
  2. Right-click on one of the selected surfaces and choose “Make Group” from the context menu. This step groups all selected surfaces into a single object.
  3. Solidify your grouped object by right-clicking on it again, selecting “Solid Tools”, and clicking “Solidify”. This operation ensures that all edges are connected, forming a closed volume without any gaps or holes.


You have successfully created a solid model in SketchUp! Now you can proceed with further refinements such as adding details, textures, and colors to enhance the visual representation of your design.

Remember, practice makes perfect. The more you experiment with SketchUp’s tools and features, the better you will become at creating intricate solid models. So keep exploring and let your creativity soar!
