Drawing Lines, Shapes, and 3D Objects绘制线条、形状和三维对象

No matter how simple or complex your model, every model in SketchUp is really just edges and faces. The drawing tools enable you to create those edges and faces.无论你的模型有多简单或多复杂，SketchUp中的每个模型实际上都只是边和面。绘图工具使您能够创建这些边和面。

If you’re a beginner to drawing in SketchUp, start simple:如果您是SketchUp绘图的初学者，请从简单开始：

• Learn how drawing lines and shapes in 3D is different from drawing in 2D. Make sure you understand a few drawing basics and concepts, like how to align lines and shapes to the correct drawing axis. 了解在3D中绘制线条和形状与在2D中绘制不同。确保您了解一些绘图基础知识和概念，例如如何将线条和形状对齐到正确的绘图轴。(Hint: The SketchUp inference engine can help.)（提示：SketchUp推理引擎可以提供帮助。）
• Explore the shape tools and handy selection techniques.探索形状工具和方便的选择技巧。
• Discover all the ways you can push/pull your geometry into 3D.探索将几何体推入/拉入3D的所有方法。
• Draw outside the box with arcs.在方框外画圆弧。

If you’re eager to draw detail and complex 3D models, these Help Center articles can help you expand your drawing skills:如果您渴望绘制细节和复杂的3D模型，这些帮助中心文章可以帮助您扩展绘图技能：

• To make curved faces look more polished, check out how to soften round edges so they look smooth.为了使曲面看起来更光滑，请查看如何软化圆角，使其看起来更光滑。
• To move beyond basic shapes, you need to know how to divide and split faces, move entities, copy entities, erase lines and faces, flip and rotate entities, scale entities, and extrude shapes along a path with the Follow Me tool.要超越基本形状，您需要知道如何使用“跟随我”工具沿路径分割和拆分面、移动实体、复制实体、擦除线条和面、翻转和旋转实体、缩放实体以及拉伸形状。
• You can also model complex shapes with the Solid Tools, which enable you to modify 3D shapes by choosing how one shape adds to or subtracts from a second shape.您还可以使用Solid Tools对复杂的形状进行建模，这使您能够通过选择一个形状如何添加到第二个形状或从中减去来修改3D形状。
• Give your model a polished look with text, a custom background, or fog.用文字、自定义背景或雾为您的模型赋予精致的外观。

If you need to draw precisely, discover how to offset a line and measure angles and distances.如果你需要精确地绘制，可以学习如何偏移一条线并测量角度和距离。

If examples help you understand how to apply and combine drawing techniques, check out the articles on creating specific shapes, such as a cone or sphere, and objects, such as a chair or building footprint.如果示例有助于您理解如何应用和组合绘图技术，请查看有关创建特定形状（如圆锥体或球体）和对象（如椅子或建筑足迹）的文章。

Before you know it, you’ll be modeling your house, that custom dining room table you’ve been wanting to make, or the modern storefront that you envision (where others see only a dilapidated parking lot).不知不觉中，你将为你的房子、你一直想做的定制餐桌或你想象中的现代店面（其他人只看到一个破旧的停车场）建模。
