Manual:All workbenches at a glance/zh-cn

FreeCAD 的新用户面临的一个最大困难，是不知道在哪个工作台中找到某个特定工具. 下面的表中是最重要的工作台及其工具. 更完整的列表，请参阅 FreeCAD 文档中的每个工作台的页面.

四个工作台设计成了结对工作，其中一个完全包含在另一个中. Arch 包含所有的 Draft 工具，PartDesign 包含所有的 Sketcher 工具. 但是为清楚起见，下面分开来讲.

Part
Part 工作台提供了处理实体零件的基本工具：基础几何体，例如立方体和球体，以及简单的几何运算和布尔运算. 作为与 OpenCasCade 的主要锚点，Part 工作台提供了 FreeCAD 几何系统的基础设施，几乎所有其他工作台都生成基于 Part 的几何对象.

Draft
Draft 工作台提供了执行基本 2D CAD 绘图任务的工具：直线，圆圈，等等，以及一些通用的便捷工具，例如移动，旋转和缩放，另外还提供了几种绘图辅助工具，例如网格和捕捉. Draft 工作台主要用于绘制Arch 对象的引导线，但是也可以当作 FreeCAD 的“瑞士军刀”.

Sketcher
Sketcher 工作台包含用于构建和编辑复杂 2D 对象的工具，称为草图(sketch). 这些草图内的几何形状可以通过使用约束来精确地定位和关联. 这些草图(sketch)对象主要是 PartDesign 几何体的构建模块，但在 FreeCAD 各处都有用.

Part Design
Part Design 工作台包含用于构建实体零件的高级工具，还包含 Sketcher 中的所有工具. 由于Part Design 工作台只能生成实体形状（Part Design的第一规则），因此在设计用于制造的部品或用于 3D 打印的零件时，Part Design 是主工作台，您将始终获得可打印的对象.

Arch
Arch 工作台包含用于处理 BIM 项目（土木工程和建筑）的工具，还包含 Draft 工作台中的所有工具. Arch 工作台的主要用途是创建 BIM 对象或为使用其他工作台构建的对象提供 BIM 属性，以便导出到IFC 里.

Drawing
Drawing 工作台处理 2D 工程图纸的创建和操作，用于在 2D 平面上显示 3D 工作成果. 然后，可以将这些图纸 SVG 或 DXF 格式，用其它 2D 应用程序打开，也可导出为 PDF 文件，或者打印出来.

其他内置工作台
上面概括介绍了 FreeCAD 最重要的几个工具，但还有更多工作台可用，包括：


 * The Mesh Workbench allows to work with polygon meshes. Although meshes are not the preferred type of geometry to work with in FreeCAD, because of their lack of precision and support for curves, meshes still have a lot of uses, and are fully supported in FreeCAD. The Mesh Workbench also offers a number of Part-to-Mesh and Mesh-to-Part tools.
 * The Raytracing Workbench offers tools to interface with external renderers such as povray or luxrender. Right from inside FreeCAD, this workbench allows you to produce high-quality renderings from your models.
 * The Spreadsheet Workbench permits the creation and manipulation of spreadsheet data, that can be extracted from FreeCAD models. Spreadsheet cells can also be referenced in many areas of FreeCAD, allowing to use them as master data structures.
 * The FEM Workbench deals with Finite Elements Analysis, and permits the performing of pre- and post-processing FEM calculations and to display the results graphically.

External workbenches
A number of other very useful workbenches produced by FreeCAD community members also exist. Although they are not included in a standard FreeCAD installation,they are easy to install as plug-ins. They are all referenced in the FreeCAD-addons repository. Among the most developed are:


 * The Drawing Dimensioning Workbench offers many new tools to work directly on Drawing Sheets and allow you to add dimensions, annotations and other technical symbols with great control over their aspect.
 * The Fasteners Workbench offers a wide range of ready-to-insert fasteners objects like screws, bolts, rods, washers and nuts. Many options and settings are available.
 * The Assembly2 Workbench offers a series of tools to mount and work with assemblies.
