Whatever your experience level or modeling style, the way you model impacts SketchUp’s performance. 无论您的经验水平或建模风格如何，建模方式都会影响SketchUp的性能。Using the recommended system requirements helps, but there are a few other things you can do to optimize your SketchUp experience.使用推荐的系统要求会有所帮助，但您还可以做一些其他事情来优化SketchUp体验。
Update, Update, Update!更新，更新，更新！
Make sure you are using the latest version of SketchUp. Staying current with updates helps you make sure SketchUp runs at peak efficiency. Supported versions of SketchUp should prompt you to install an update when one is available. 确保您使用的是最新版本的SketchUp。保持最新更新有助于确保SketchUp以最高效率运行。SketchUp的支持版本应在更新可用时提示您安装更新。If you aren’t sure, you can always check for updates. 如果你不确定，你可以随时检查更新。For Windows users, go to the Help menu and click Check for Update. 对于Windows用户，请转到“帮助”菜单，然后单击“检查更新”。For MacOS, go to the SketchUp menu and click Check Web for Update.对于MacOS，转到SketchUp菜单，然后单击检查Web是否更新。
Your computer should be updated with all the latest updates as well. 您的计算机也应更新为所有最新更新。For more information, or if you are having other performance issues, see Graphics and Performance.有关更多信息，或者如果您有其他性能问题，请参阅图形和性能。
Optimized Modeling Techniques优化建模技术
SketchUp renders everything you do as you do it. Whether you are drawing, orbiting, or editing, SketchUp is using resources to update what you see in the drawing window. SketchUp会实时渲染您所做的一切。无论是绘图、动态观察还是编辑，SketchUp都会使用资源来更新您在绘图窗口中看到的内容。The more edges, faces, and materials you have in a model, the more resources SketchUp needs to use. Minimizing these aspects of your model, also known as keeping your model light, can really improve the way SketchUp performs.模型中的边、面和材质越多，SketchUp需要使用的资源就越多。最小化模型的这些方面，也称为保持模型轻量化，可以真正改善SketchUp的性能。
Here are a few ways to keep your model light:以下是一些保持模型轻量化的方法：
Stick to simple styles. Whenever possible turn off shadows, textures, and special display effects while modeling. 坚持简单的风格。建模时尽可能关闭阴影、纹理和特殊显示效果。A great way to do this is to create two separate styles – one for modeling and another for presentation. 一个很好的方法是创建两个单独的样式——一个用于建模，另一个用于演示。See Fast Styles for more information.有关详细信息，请参阅快速样式。Components are your friends. When you use the same entity multiple times in a model, make it a component, then make copies of that component. 组件是你的朋友。当您在模型中多次使用同一实体时，将其作为组件，然后复制该组件。Multiple instances of a component are lighter weight than multiple copies of an entity or group.组件的多个实例比实体或组的多个副本重量轻。Hide geometry you don’t need. The more visible geometry the slower SketchUp will run. Hiding geometry you don’t need improves performance. One of the best ways to hide geometry is by controlling its visibility with tags. 隐藏不需要的几何图形。几何图形越明显，SketchUp的运行速度就越慢。隐藏不需要的几何体可以提高性能。隐藏几何体的最佳方法之一是使用标记控制其可见性。For more information see Controlling Visibility with Tags.有关详细信息，请参阅使用标记控制可见性。Image file format matters. If you import images into your model you may want to use a lighter file format for that image. While TIFF files are high quality, they also tend to be larger files and take more resources to display. Try using an image in JPEG format instead.图像文件格式很重要。如果将图像导入模型，则可能需要为该图像使用较轻的文件格式。虽然TIFF文件质量很高，但它们也往往是更大的文件，需要更多的资源来显示。请尝试使用JPEG格式的图像。Disable fog and shadows. Special effects like fog and shadows give SketchUp more work to do and aren’t really necessary if you are still drawing or editing your model. You can turn off both in the View options.禁用雾和阴影。雾和阴影等特殊效果为SketchUp提供了更多的工作，如果您仍在绘制或编辑模型，则没有必要这样做。您可以在“视图”选项中同时关闭这两个选项。Purge unused data from your model. Your model stores all the components, styles, and materials you’ve added while modeling even after you’ve erased or replaced them. This can be handy if you need to use them later, but if you won’t they will just hang out behind the scenes and take up resources that could be used for other parts of your model. 从模型中清除未使用的数据。您的模型会存储您在建模时添加的所有组件、样式和材质，即使在您删除或替换它们之后也是如此。如果你以后需要使用它们，这可能会很方便，但如果你不愿意，它们只会在幕后闲逛，占用可用于模型其他部分的资源。You can purge the following types of data:您可以清除以下类型的数据：
To purge all unused items at once select Window>Model Info>Statistics then click Purge Unused.要一次清除所有未使用的项目，请选择“窗口”>“模型信息”>“统计信息”，然后单击“清除未使用项”。
