===Drawing objects===

The created 2D objects can be used for general drafting in a way similar to Inkscape or Autocad. These 2D shapes can also be used as the base components of 3D objects created with other workbenches, for example, the [[Part Workbench|Part]] and [[Arch Workbench|Arch Workbench]]es. Conversion of Draft objects to [[Sketcher Workbench|Sketches]] is also possible, which means that the shapes can also be used with the [[PartDesign Workbench|PartDesign Workbench]] for the creation of solid bodies.

FreeCAD is primarily a 3D modelling application, and thus its 2D tools aren't as advanced as in other drawing programs. If your primary goal is the production of complex 2D drawings and [[DXF|DXF]] files, and you don't need 3D modelling, you may wish to consider a dedicated software program for technical drafting such as [https://en.wikipedia.org/wiki/LibreCAD LibreCAD], [https://en.wikipedia.org/wiki/QCad QCad], TurboCad, and others.

The FreeCAD Draft Workbench Icon

草稿坊能在現有文件中快速建立平面物件,且提供數種工具用時事後修改。若干工具同時用於其他 FreeCAD 物件,不僅限於草稿坊。且提供完整 snapping system, 以及數種功能來管理物件與設定。

The created 2D objects can be used for general drafting in a way similar to Inkscape or Autocad. These 2D shapes can also be used as the base components of 3D objects created with other workbenches, for example, the Part and Arch Workbenches. Conversion of Draft objects to Sketches is also possible, which means that the shapes can also be used with the PartDesign Workbench for the creation of solid bodies.

FreeCAD is primarily a 3D modelling application, and thus its 2D tools aren't as advanced as in other drawing programs. If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, you may wish to consider a dedicated software program for technical drafting such as LibreCAD, QCad, TurboCad, and others.

Draft Workbench Example

Drawing objects

These are tools for creating objects.

Modifying objects

These are tools for modifying existing objects. They work on selected objects, but if no object is selected, you will be invited to select one.

Many operation tools (move, rotate, array, etc.) also work on solid objects (Part, PartDesign, Arch, etc.).

Utility tools

Additional tools available from the menu Draft → Utilities, or via the right-click context menu, depending on the selected object.

Preferences

  • Preferences: general preferences for the working plane and the drawing tools.
  • Import-Export Preferences: preferences available for importing from and exporting to different file formats.

Additional features

  • Coordinates: enter coordinates instead of clicking on the 3D view to define a new point.
  • Constraining: limit the pointer to horizontal or vertical movements relative to a previous point.
  • Snapping: place new points on special places on existing objects or on the grid.
  • Copy Mode: All modification tools can either modify the selected objects or create a modified copy of them. Pressing and holding Alt while the object is being modified, e.g. moved or rotated, creates a copy when the key is released.
  • Construction Mode: Allows you to create geometries separate from the rest by simply switching them on and off.
  • Working plane: allows you to select a surface on which to build your shapes.

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

Scripting

The Draft tools can be used in macros and from the Python console by using the Draft API.

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.
