Creating Custom Components in SketchUp

Creating custom components in SketchUp allows users to design and model unique objects that can be reused and shared with others. Custom components offer a range of benefits, including increased efficiency, improved accuracy, and enhanced collaboration. In this article, we will explore the process of creating custom components in SketchUp, from basic concepts to advanced techniques. We will also discuss the advantages of using custom components and provide practical examples to illustrate their application. Whether you are a beginner or an experienced SketchUp user, this article will provide valuable insights and guidance to help you create custom components that meet your specific design needs.

Understanding Components in SketchUp

Before diving into the process of creating custom components, it is important to have a clear understanding of what components are in SketchUp. In SketchUp, a component is a group of geometry that can be easily reused and edited. Components can be anything from simple objects like chairs or tables to complex structures like buildings or landscapes. When you create a component, it becomes a separate entity within your model, allowing you to make changes to one instance of the component and have those changes automatically applied to all other instances.

Components in SketchUp have several key characteristics:

  • Reusability: Components can be reused multiple times within a model or across different models. This saves time and effort by eliminating the need to recreate the same geometry over and over again.
  • Consistency: When you make changes to a component, all instances of that component are automatically updated. This ensures consistency throughout your model and reduces the risk of errors or inconsistencies.
  • Organization: Components help organize your model by grouping related geometry together. This makes it easier to navigate and edit complex models.
  • Sharing: Components can be shared with others, allowing for collaboration and the exchange of design ideas.

Now that we have a clear understanding of what components are in SketchUp, let’s explore the process of creating custom components.

Creating a Basic Custom Component

The process of creating a custom component in SketchUp involves a few simple steps. Let’s start by creating a basic custom component:

  1. Select the geometry you want to turn into a component. This can be a single object or a group of objects.
  2. Right-click on the selected geometry and choose “Make Component” from the context menu.
  3. In the “Create Component” dialog box, give your component a name and choose any additional options you want, such as setting the component’s axes or making it a 2D component.
  4. Click “Create” to create the component.

Once you have created a component, it will appear in the “Components” window, which can be accessed from the “Window” menu. You can then drag and drop the component into your model to create instances of it. Any changes you make to one instance of the component will be automatically applied to all other instances.

Creating a basic custom component is a straightforward process, but SketchUp also offers advanced features and techniques for creating more complex components. Let’s explore some of these advanced techniques.

Advanced Techniques for Creating Custom Components

SketchUp provides several advanced techniques for creating custom components that offer greater flexibility and control over your designs. Here are some of the advanced techniques you can use:

1. Adding Dynamic Attributes

Dynamic attributes allow you to add interactive properties to your components. For example, you can create a door component with dynamic attributes that allow you to open and close the door. To add dynamic attributes to a component, you can use SketchUp’s Dynamic Components feature. This feature allows you to define custom attributes and create rules that control how those attributes behave.

For example, you can create a dynamic attribute called “Door State” and define two possible values: “Open” and “Closed”. You can then create a rule that says when the “Door State” attribute is set to “Open”, the door component should rotate 90 degrees to simulate opening. This allows you to create interactive components that respond to user input.

2. Creating Nested Components

Nested components are components that contain other components. This allows you to create complex assemblies by combining multiple components together. For example, you can create a chair component that consists of a seat component, a backrest component, and four leg components. By nesting these components together, you can easily assemble and disassemble the chair as needed.

To create a nested component, simply select the components you want to include and right-click on them. Choose “Make Component” from the context menu, and the selected components will be combined into a single nested component.

3. Using Component Options

Component options allow you to define different variations of a component. For example, you can create a window component with different options for the frame material, glass type, and opening style. By using component options, you can quickly switch between different variations of a component without having to recreate it from scratch.

To create component options, you can use SketchUp’s “Component Options” dialog box. In this dialog box, you can define different attributes and their possible values. You can then create rules that control how the component behaves based on the selected options.

4. Creating Dynamic Sections

Dynamic sections allow you to create sections of your model that can be dynamically adjusted. This is useful for creating cutaway views or exploded views of your components. To create a dynamic section, you can use SketchUp’s “Section Plane” tool.

The “Section Plane” tool allows you to create a plane that cuts through your model. You can then adjust the position and orientation of the section plane to control which parts of your model are visible and which parts are hidden. By combining section planes with components, you can create dynamic sections that update automatically when the model changes.

The Advantages of Using Custom Components

Using custom components in SketchUp offers several advantages over creating geometry from scratch for each project. Here are some of the key advantages:

1. Increased Efficiency

Creating custom components allows you to reuse geometry, saving time and effort. Instead of recreating the same objects over and over again, you can simply drag and drop pre-made components into your model. This significantly speeds up the design process and allows you to focus on the unique aspects of your project.

2. Improved Accuracy

Custom components ensure consistency and accuracy throughout your model. When you make changes to a component, those changes are automatically applied to all instances of that component. This eliminates the risk of errors or inconsistencies that can occur when manually editing geometry.

3. Enhanced Collaboration

Custom components can be easily shared with others, allowing for collaboration and the exchange of design ideas. By creating and sharing components, you can work together with colleagues or clients to develop and refine your designs.

4. Flexibility and Customization

Custom components offer greater flexibility and customization options compared to manually creating geometry. With custom components, you can easily modify and adjust the properties of your objects, such as size, material, or style. This allows you to explore different design options and make changes on the fly.


Creating custom components in SketchUp is a powerful tool that allows you to design and model unique objects with ease. By understanding the basic concepts of components and exploring advanced techniques, you can create custom components that meet your specific design needs. The advantages of using custom components, such as increased efficiency, improved accuracy, enhanced collaboration, and flexibility, make them an essential part of any SketchUp workflow.
