<p><b>草图工作台</b>用于创建二维几何，用于<b><a href="https://www.freecadweb.org/wiki/index.php?title=PartDesign_Workbench/zh-cn&action=edit&redlink=1" class="new" title="PartDesign Workbench/zh-cn (page does not exist)">零件设计工作台</a></b>和其他工作台。
|
||
通常，2D几何被认为是大多数CAD模型的起点 - 简单的2D草图可以“挤压”成3D形状，另外可以使用2D草图在该形状的表面中创建凹坑，并且可以使用草图在3D对象的表面定义“垫高”（挤压）。
|
||
随着<a href="https://www.freecadweb.org/wiki/index.php?title=Part_Module/zh-cn&action=edit&redlink=1" class="new" title="Part Module/zh-cn (page does not exist)">部件模块|布尔运算</a>，草图编辑器形成了生成实体形状设计的核心。
|
||
</p><p>草图工作台本身具有约束条件 - 允许将2D形状约束到精确的几何定义。以及一个约束求解器，它计算二维几何约束范围，并允许对草图自由度的交互式探索。

|
||
<p>为了解释草图编辑器的工作原理，将其与“传统的”起草方式进行比较可能是有用的。
|
||
</p>
|

<h4><span class="mw-headline" id=".E4.BC.A0.E7.BB.9F.E8.B5.B7.E8.8D.89">传统起草</span></h4>
|
||
<p>CAD绘图的传统方式继承于旧的<a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Drawing_board">绘图板</a>. <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Multiview_orthographic_projection">正交（2D）视图</a> 手动绘制，用于生产技术图纸（也称为蓝图）。对象被精确地绘制到预期的尺寸或尺寸上。如果要从（0,0）开始绘制长度为100mm的水平线，您可以激活线条工具，点击屏幕或输入第一个点的（0,0）坐标，然后再次点击或在（100,0）处输入第二点坐标。或者你会画你的线，而不考虑它的位置，然后移动它。绘制几何图形后，可以向其添加尺寸。
|
||
</p>
|
||
<h4><span class="mw-headline" id=".E7.BA.A6.E6.9D.9F.E8.8D.89.E5.9B.BE">约束草图</span></h4>
|
||
<p><b>草图</b>远离这个逻辑。对象不需要完全按照您的意图进行绘制，因为它们将在稍后被约束定义。对象可以松散绘制，只要不受约束，就可以进行修改。它们实际上是“浮动”，可以移动，拉伸，旋转，缩放等等。这在设计过程中给予了很大的灵活性。
|
||
</p>
|
||
<h4><span class="mw-headline" id=".E4.BB.80.E4.B9.88.E6.98.AF.E7.BA.A6.E6.9D.9F.EF.BC.9F">什么是约束？</span></h4>
|
||
<p>使用约束来限制对象的自由度。例如，没有约束的线条具有4 <a href="#Degrees_Of_Freedom">自由度</a>（简写为“DOF”）：可以水平或垂直移动，可以被拉伸，并且可以旋转。
|
||
</p><p>应用水平或垂直约束或角度约束（相对于另一条线或与其中一条轴）将限制其旋转能力，从而使其具有3个自由度。锁定其原点之一的点将消除另外2个自由度。并且应用维度约束将消除最后的自由度。然后，该行被认为是“完全受限制的”。
|
||
</p><p>多个对象可以彼此约束。可以通过其中一个点与重合点约束连接两条线。可以在它们之间设置一个角度，或者它们可以垂直设置。一条线可以与弧或圆相切，依此类推。具有多个对象的复杂草图将具有多种不同的解决方案，并使其“完全受约束”，这意味着基于所应用的约束只能达到其中一种可能的解决方案。
|
||
</p><p>有两种约束：几何和尺寸。它们在下面的<a href="#The_tools">'工具'</a>部分中详细介绍。
|
||
</p>

<h3><span class="mw-headline" id=".E8.8D.89.E5.9B.BE.E7.BC.96.E8.BE.91.E5.99.A8.E4.B8.8D.E6.93.85.E9.95.BF.E4.BA.8E">草图编辑器不擅长于</span></h3>
|
||
<p>草图编辑器不打算制作2D蓝图。草图一旦用于生成实体特征后，会自动隐藏。约束仅在草图编辑模式下可见。
|
||
</p><p>如果您仅需要生成2D视图进行打印，并不想创建3D模型，请查看<a href="https://www.freecadweb.org/wiki/index.php?title=Draft_Module/zh-cn&action=edit&redlink=1" class="new" title="Draft Module/zh-cn (page does not exist)">底图工作台</a>（请注意，底图工作台也可用于创建此时草图编辑器中不可用的2D几何，如B-Splines。）

|
||
<p>草图总是二维（2D）。要创建一个实体，创建单个封闭区域的2D草图，然后垫高或旋转以添加第三维，从2D草图创建3D实体。
|
||
</p><p>如果草图具有彼此交叉的段，其中一个点不直接位于段上的位置，或相邻段的端点之间存在间隙的位置，垫高或旋转将不会创建一个实体。这个规则的例外是它不适用于构造（蓝色）几何对象。
|
||
</p><p>在封闭区域内，我们可以有较小的非重叠区域。当创建3D实体时，这些将变为空白。

|
||
<p>每个CAD用户随着时间的推移发展自己的工作方式，但跟随一些有用的一般原则。
|
||
</p>
|
||
<ul><li> 一系列简单的草图比单个复杂的草图更容易管理。例如，可以为基础3D特征（衬垫或旋转）创建第一个草图，而第二个可以包含孔或切口（凹坑）。一些细节可以省略，稍后将作为3D功能实现。如果太多，你可以选择避免草图中的圆角，并将其添加为3D功能。</li>
|
||
<li> 始终创建一个封闭的配置文件，或者你的草图不会产生实体，而是一组开放的面。如果你不希望将某些对象包含在实体创建中，请使用“构造模式”工具将其转换为构造元素。</li>
|
||
<li> 使用自动约束特性来限制你必须手动添加的约束数量。</li>
|
||
<li> 作为一般规则，首先应用几何约束，然后应用尺寸约束，并最后锁定草图。但请记住：规则被破坏。如果你在操作草图时遇到问题，在完成配置文件之前先限制几个对象可能很有用。</li>
|
||
<li> 如果可能，将草图中心定位到具有锁定约束的原点（0,0）。如果你的草图不对称，请将其中一个点定位到原点，或者为锁定距离选择好的圆角参数。在v0.12中，外部约束（将草图约束到现有3D几何像边缘或其他草图）未实现。这意味着要将以下草图定位到你的第一个草图中，你需要手动设置相对于你的第一个草图的距离。一个基于原点的（25,75）的锁定约束比（23.47,73.02）更容易记住。</li>
|
||
<li> 如果你有可能在长度约束和水平或垂直距离约束之间进行选择，则选择后者。水平和垂直距离约束在计算上更便宜。</li>
|
||
<li> 一般来说，最好使用的约束是：水平和垂直约束;水平和垂直长度约束;点对点相切。如果可能，限制使用这些：一般长度约束;边缘到边缘相切;固定点到线约束;对称约束</li></ul>
