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. 

Drawing 3D models in SketchUp requires a lot of back and forth between your keyboard and mouse. As you become a more experienced SketchUp modeler, you develop a sense of what commands and tools you use most often and what you do and don't like about the default keyboard and mouse settings.

In SketchUp, you can set a few preferences for how the software works overall and how files are saved.To access these preferences, select Window > Preferences (Windows) or SketchUp > Preferences (MacOS) from the menu bar. Most of these preferences are on the General pane, which you click in the sidebar on the left. As shown in the following figure, your options include Saving preferences at the top and Software Updates preferences at the bottom.
