Whatever your experience level or modeling style, the way you model impacts SketchUp’s performance. Using the recommended system requirements helps, but there are a few other things you can do to optimize your SketchUp experience. 

The template you choose when you first create a new model determines a lot of your model’s settings. SketchUp includes a few templates that represent the most common applications including architecture, construction, urban planning, and landscaping among others. You can select from one of these default templates from the Home section of the Welcome Window.
