Creating a 3D Model创建3D模型

Creating a 3D model is easy with SketchUp, but it can be a lot easier when you know about basic modeling techniques. Then, once you know the basics, you can dive into some of the more advanced techniques to help create stunning models for your projects.使用SketchUp创建3D模型很容易，但当你了解基本的建模技术时，它会变得容易得多。然后，一旦你掌握了基础知识，你就可以深入了解一些更先进的技术，帮助你为项目创建令人惊叹的模型。

In this section we cover the features and tools available to help you create models in SketchUp including:在本节中，我们将介绍可用于帮助您在SketchUp中创建模型的功能和工具，包括：

• Drawing Lines, Shapes, and 3D Objects 绘制线条、形状和三维对象and 和Viewing a Model 查看模型can help with basic drawing techniques like basic shapes, complex techniques like flipping and stretching, moving around your model, and inspecting individual entities in your model.可以帮助您掌握基本的绘图技术，如基本形状，复杂的技术，如翻转和拉伸，在模型中移动，以及检查模型中的单个实体。
• Choosing a Style 选择风格and 和Applying Colors, Photos, Materials, and Textures 应用颜色、照片、材质和纹理both explain how to use SketchUp’s predefined styles and materials, or your own creations, to customize edges, faces, and backgrounds in your models.两者都解释了如何使用SketchUp的预定义样式和材质或您自己的创作来自定义模型中的边、面和背景。
• In Adding Premade Components and Dynamic Components添加预制组件和动态组件, learn where to find premade components made by the SketchUp community and how to add them into your models.，了解在哪里可以找到SketchUp社区制作的预制组件，以及如何将它们添加到模型中。
• Organizing a Model 组织模型and 和Classifying Objects 对对象进行分类cover how to group geometry, use the outliner, use the classifier, and control visibility with tags (SketchUp’s version of layers).介绍如何对几何图形进行分组、使用大纲视图、使用分类器以及使用标签控制可见性（SketchUp的图层版本）。
• Modeling Terrain and Other Rounded Shapes 模拟地形和其他圆形形状can help give your model some context by importing terrain data or creating it yourself.通过导入地形数据或自己创建，可以帮助您的模型提供一些上下文。
