Draft Workbench

Introduction
The Draft Workbench allows you to draw simple 2D objects, and offers several tools to modify them afterwards. It also provides tools to define a working plane, a grid, and a snapping system to precisely control the position of your geometry.

The created 2D objects can be used for general drafting in a way similar as is done with 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, or others.

Preferences

 * [[Image:Preferences-draft.svg|32px]] Preferences: general preferences for the working plane and the drawing tools.
 * [[Image:Preferences-import-export.svg|32px]] Import Export Preferences: preferences available for importing from and exporting to different file formats.

File formats
These are functions for opening, importing or exporting other file formats. Opening will open a new document with the contents of the file, while importing will append the contents of the file to the current document. Export will save the selected objects to a file. If nothing is selected, all objects will be exported. Be aware that the purpose of the Draft Module is to work with 2D objects, so those import routines focus only on 2D objects, and although DXF and OCA formats also support object definitions in 3D space (objects are not necessarily flat), they will not import volumetric objects such as meshes, 3D surfaces, etc., but rather lines, circles, texts or flat shapes. Currently supported file formats are: The Draft module provides FreeCAD with importers and exporters for the following file formats:


 * Autodesk .DXF: imports and exports Drawing Exchange Format files created with 2D CAD applications. See also FreeCAD and DXF Import.
 * Autodesk .DWG: imports and exports DWG files via the DXF importer, when the ODA Converter utility is installed. See also FreeCAD and DWG Import.
 * SVG: imports and exports Scalable Vector Graphics files created with vector drawing applications.
 * Open Cad format .OCA: imports and exports OCA/GCAD files, a potentially new open CAD file format.
 * Airfoil Data Format .DAT: imports DAT files describing Airfoil profiles.

Install importers

 * FreeCAD and DWG Import: Imports and exports DWG files
 * FreeCAD and DXF Import: Imports and exports DXF files

Additional features

 * 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 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
Test Workbench.

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

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.

Use this to test that all objects are produced correctly.

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

Where is the toplevel directory where the software was installed; for example, in Linux it may be.
