Introduction

简介

您可以利用底图工作台来绘制简单的2D对象,再利用其提供的其他工具来修改这些对象。此工作台提供了工具来定义工作平面、网格。另外,还有一个snapping系统可助您精确地控制几何体的位置。

用户创建的2D对象能以类似于Inkscape或Autocad中的方式用于通用绘图。这些2D图形也可用作零件工作台建筑工作台等其他工作台所创3D对象的基本组件。另外,也可以将底图对象转换至草图工作台,这意味着能够在零件设计工作台中利用这些图形来创建实体。

FreeCAD是一款以3D建模为主的应用软件,这使它的2D工具并非如其他绘图程序那样高级。如果您的主要目的是复杂的2D绘图与处理DXF文件,并不是3D建模,那么不妨考虑一款关于技术制图的专用软件,例如LibreCAD, QCad, TurboCad以及其他类似程序。

Draft Workbench Example

绘制对象

下面来介绍一些用于创建对象的工具。

Annotation objects

修改对象

以下这些工具用来修改已存在的对象。这写工具处理的是用户选定的对象,如果没有选择待处理对象,系统会提醒你选择一个。

许多工具(移动, 旋转, 阵列等)也可用于处理实体对象(零件, 零件设计, 建筑等)。

  • Shape 2D View: creates a 2D object which is a flattened 2D view of a 3D object.

Obsolete

This command is considered obsolete because the Drawing Workbench is obsolete. However, the command itself is still available.

These commands have been removed from the interface.

Draft Tray toolbar

The Draft tray toolbar appears when the workbench is started, and allows selecting the working plane, together with some visual properties like the line color, shape color, text size, line width, and automatic group.

Draft Snap toolbar

The Draft Snap toolbar allows selecting the currently snapping mode. Its button keep depressed when a mode is active.

实用工具

Utility menu

其他工具可从Draft → Utilities菜单处找到。或者右击当前的环境菜单(context menu),具体可用工具取决于当前所选对象。

Obsolete

These tools were removed from the interface in v0.19 because they no longer had any purpose.

首选项

文件格式

底图模块为FreeCAD提供了下列格式文件的导出、导出服务:

Install importers

其他功能

Unit tests

See also: Test Workbench.

To run the unit tests of the workbench execute the following from the operating system terminal.

freecad -t TestDraft

脚本

借助Draft API即可在Python控制台中使用各种底图工具。

The workbench includes a module to create samples of all objects in a new document. introduced in version 0.19

Use this to test that all objects are produced correctly.

import drafttests.draft_test_objects as dto
doc = dto.create_test_file()

Inspecting the code of this module is useful to understand how to use the programming interface.

$INSTALLDIR/Mod/Draft/drafttests/draft_test_objects.py

Where $INSTALLDIR is the toplevel directory where the software was installed; for example, in Linux it may be /usr/share/freecad.

Test objects for the Draft Workbench.
