工作台

Other languages:

像许多现代设计应用程序，如Revit或CATIA，FreeCAD基于工作台的概念。工作台可以被认为是为特定任务分组的一组工具。在一个传统的家具车间里，你有一个工作桌子给木材工作的人，另一张桌子给金属件工作的人，也可能有第三张桌子给把所有这些部件组装在一起的人。

FreeCAD, like many modern design applications such as Revit or CATIA, is based on the concept of Workbench. A workbench can be considered as a set of tools specially grouped for a certain task. In a traditional furniture workshop, you would have a work table for the person who works with wood, another one for the one who works with metal pieces, and maybe a third one for the guy who mounts all the pieces together.

在FreeCAD中，相同的概念也适用。工具根据其相关任务分为工作台。

当您从一个工作台切换到另一个工作台时，界面上可用的工具发生变化。工具栏，命令栏和界面的其他部分可以切换到新的工作台，但是您的场景的内容不会改变。例如，您可以使用草图工作台开始绘制2D形状，然后使用零件工作台进一步处理它们。

请注意，有时工作台被称为“模块”。但是，工作台和模块是不同的实体。模块是FreeCAD的任何扩展，而Workbench是一个特殊的GUI配置，可以组合一些工具栏和菜单。通常每个模块都包含自己的工作台，因此交叉使用名称。

内建的工作台

每个FreeCAD安装都可以使用以下工作台：

The Arch Workbench for working with architectural elements.
~~The Complete Workbench hold all commands and features from all the modules and workbenches which met certain quality criteria.~~ Deprecated in v0.17
The Draft Workbench contains 2D tools and basic 2D and 3D CAD operations.
The Drawing Workbench was used for displaying your 3D work on a 2D sheet but has now been deprecated, it is still needed to read old FreeCAD files that contain a Drawing object originally made with this workbench. See TechDraw Workbench, which is a more advanced replacement.
The FEM Workbench provides Finite Element Analysis (FEA) workflow.

The Image Workbench for working with bitmap images.
The Inspection Workbench is made to give you specific tools for examination of shapes. It is still in development.
The Mesh Workbench for working with triangulated meshes.
The OpenSCAD Workbench for interoperability with OpenSCAD and repairing Constructive Solid Geometry (CSG) model history.
The Part Workbench for working with CAD parts.

The Part Design Workbench for building Part shapes from sketches.
The Path Workbench is used to produce G-Code instructions. It is still in a stage of development.
The Plot Workbench is used to edit and save output plots created from other modules and tools.
The Points Workbench for working with point clouds.
The Raytracing Workbench for working with ray-tracing (rendering)

The Reverse Engineering Workbench is intended to provide specific tools to convert shapes/solids/meshes into parametric FreeCAD-compatible features. (under development)
The Robot Workbench for studying robot movements.
The Ship Workbench FreeCAD-Ship works over Ship entities, that must be created on top of provided geometry.
The Sketcher Workbench for working with geometry-constrained sketches.
The Spreadsheet Workbench for creating and manipulating spreadsheet data.

The Start Center Workbench allows you to quickly jump to one of the most common workbenches.
The Surface workbench provides tools to create and modify surfaces. It is similar as the Part Shape builder Face from edges.
The TechDraw Workbench is the more advanced and feature-rich successor of Drawing
The Test Framework Workbench is for debugging FreeCAD.
The Web Workbench provides you with a browser window instead of the 3D-View within FreeCAD.

外部工作台

FreeCAD工作台很容易在Python中编程，所以很多人在FreeCAD代码库之外开发了额外的工作台。外部工作台页面有一些关于其中的一些信息和教程，FreeCAD Addons项目旨在收集它们，并使其可以从FreeCAD中轻松安装。

The external workbenches page lists all that are known to this community. Most are easily installable from within FreeCAD, using the Addon Manager, found under menu Tools → Addon manager.
