Manual:The FreeCAD Interface/zh-cn

FreeCAD 使用 Qt 框架绘制和管理其界面. 该框架广泛用于很多应用程序，因此 FreeCAD 的界面非常经典，没有特别的难以理解之处. 大多数按钮都是标准按钮，可以在您希望的位置找到，例如：，等等. 这是FreeCAD 第一次打开时的外观，安装后，显示启动中心.



启动中心是一个方便的“欢迎屏幕”，为新手提供有用的信息，例如您一直在处理的最新文件，FreeCAD 世界中的新功能，或有关最常见工作台的快捷信息. 如果有新的稳定的FreeCAD 版本，它也会通知您.

过了一段时间，当您更熟悉 FreeCAD 时，您可能已经对首选项进行了更改，因此当FreeCAD 启动时，您会直接进入一个工作台中看到自己打开的新文档. 如果你还没有更改首选项，你只需关闭起始页面选项卡并创建一个新文档.



工作台
请注意，上面两个屏幕截图之间的某些图标已经有所不同. 这是 FreeCAD 界面中使用的最重要概念发挥作用的地方：工作台.

工作台是按专业组合在一起的工具组（工具栏按钮，菜单和其他界面控件）. 想像一个你可以让不同的人一起工作的工作坊：一个人做金属工作，另一个做木材工作. 每个人都在他们的工作室里有一张单独的桌子，上面有他/她工作用的特定工具. 虽然工作内容不同，他们的工作对象却可以相同. 类似地，FreeCAD 就是如此.

FreeCAD 界面最重要的控件是工作台选择器，你可以使用它从一个工作台切换到另一个工作台：



新用户经常对工作台感到困惑，因为要知道在哪个工作台中查找特定工具并不总是很容易. 但是他们很快就学会了，过了一会儿就会感觉很自然——意识到这是组织 FreeCAD 提供的众多工具的很便捷的方式. 工作台也可完全自定义（见下文）. 相同的工具可能出现在多个工作台中. 无论出现在哪个工作台，一个工具的按钮图标始终都是相同的.

在本手册的后面部分，你还会看到一个显示所有工作台内容的表格.

界面
Let's have a better look at the different parts of the interface:




 * The 3D view is the main component of the interface; it is where the objects you are working with are drawn and manipulated. You may have several views of the same document (or same objects), or several documents open at the same time. Each of these views may be individually undocked from the main window. You may select objects or parts of objects by clicking them, and you can pan, zoom and rotate the view with the mouse buttons. This will be explained further in the next chapter.

In addition to the 3D view panel, the following information panels are available. They may be made visible or hidden by selecting them from. The name of the panel appears in the upper left corner of the panel when it is displayed: The Tasks tab sometimes has puzzling and frustrating side-effects. If the Task tab is not empty, some FreeCAD operations will not work as expected. For example, if you have a single object in your model such as a cube, double-clicking on it will open the Tasks tab to allow you to modify the parameters characterizing the cube. If you have the Selection view open, you will see the cube's internal name listed there. The entire cube will turn green in the 3D panel, indicating the entire cube is selected. Clicking on the background will deselect the entire cube and clear the Selection view. So far, this is normal behavior. However, if you now click on a face of the cube, instead of that face being selected, nothing will be selected &mdash; because the Tasks tab has not been completed. Even if you have made no modifications to the parameters there, FreeCAD is waiting for the  (or other) button in the Tasks tab to be clicked.
 * The combo view has two tabs:
 * The Model tab shows you the contents and structure of your document above and the properties (or parameters) of the selected object(s) below. These properties are separated into two categories:
 * Data (properties which concern the geometry itself)
 * View (properties that affect how the geometry looks on screen).
 * The Tasks tab is where FreeCAD will prompt you for values specific to the workbench and tool you are currently using. For example, entering a 'length' value when the Draft Workbench Line Tool is being used. It will clear and switch back to the Model tab after the OK (or Cancel) button is pressed. Double-clicking the related object in the Model tab will usually reopen the corresponding Task tab in order to modify the settings.


 * The report view is normally hidden, but it is a good idea to open it as it will list any information, warnings or errors to help you decipher (or debug) what you may have done wrong.
 * The Python console is also hidden by default. This is where you can interact with the contents of the document using the Python language. Since every action you do on the FreeCAD interface actually executes a piece of Python code, having this open allows you to watch the code unfold in real time &mdash; allowing you a wonderful and easy way to learn a little Python on the way, almost without noticing it.
 * The tree view displays only the object tree shown under the Model tab in the combo view. It is normally hidden.
 * The property view displays only the object property information shown at the bottom of the combo view. It is normally hidden.
 * The selection view shows the names of any objects which are currently selected. These are the objects to which a workbench operation will be applied. It can be used to refine the selection by deselecting some of those objects before a workbench operation is applied.  The selection view can also be used to search for objects by name and then select them.  By default, the selection view is hidden.  While you can often determine the currently selected object(s) by looking at the object tree in the Model tab of the combo view, for complex operations requiring multiple selections and where selection is difficult it is helpful to make this view visible so you can both see the labels and count the selected objects.



Customizing the interface
The interface of FreeCAD is highly customizable. All panels and toolbars can be moved to different places or stacked one above another. They can also be closed and reopened when needed from the View menu or by right-clicking on an empty area of the interface. There are, however, many more options available, such as creating custom toolbars with tools from any of the Workbenches, or assigning and changing keyboard shortcuts.

These advanced customization options are available from the :
