In SketchUp, collections help you organize styles and easily access the ones you use most often. SketchUp includes several default collections, but you can create your own and save collections to a favorites list.The In Model styles collection is particularly helpful, because it contains all the styles currently included with your model file. To see your In Model styles, follow these steps:

SketchUp provides a lot of styles to choose from by default. If those don’t quite fit the needs of your design, you can always edit them, or even create a new one. To get started, open the Styles panel and follow these steps:To create a new style click Create New Style () on the Select tab. If you want to edit an existing style, move on to step 2.

A big part of your model's style is what you see in the background. SketchUp makes it easy to customize the background including the sky, horizon, and ground to best fit the style of your model. After all, what's the use in making a Mars Rover if it doesn't look like it's on Mars? You can customize the background colors of your model in the Styles panel by following these steps:

Styles in SketchUp are a great way to help you convey information about your model without saying a word. A Style is a collection of specific settings for edges, faces, and backgrounds.

To choose a Style: 

As you create a model in 3D, you need to view it from all sides. In SketchUp, you orbit, zoom, and pan all the time as you draw:

To create a 3D model in SketchUp, you're constantly switching among the drawing tools, views, components, and organizational tools. In this article, you find several examples that illustrate ways you can use these tools together to model a specific shape or object.The examples illustrate a few of the different applications for creating 3D models in SketchUp: woodworking, modeling parts or abstract objects, and creating buildings. The examples are loosely ordered from the simple to the complex.

The Fog panel helps you add an effect that mimics real world fog in your model. With Fog enabled, your model becomes clearer as you zoom closer to it, and less clear as you move away. To add fog-like effects to your model, follow these steps:

The red, blue, and green axes in a SketchUp model are not only starting points. These axes also serve as guides you can use throughout the modeling process. Some examples of how using the drawing axes can help with your workflows include:

In SketchUp, you can add four types of text:

With SketchUp’s Solid tools, you can create new shapes by combining or cutting one shape with another, making it easy to model an outer shell or joinery.
