Kreslicí pracovní plocha umožňuje jednoduché kreslení 2D objektů v aktuálním dokumentu a nabízí několik nástrojů pro následnou modifikaci. Některé z těchto nástrojů fungují i ve všech dalších objektech FreeCAD, nejenom v těch, které jsou vytvořeny v Kreslicí pracovní ploše. Poskytuje také kompletní uchopovací systém a několik utilit pro správu objektů a nastavení.

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.

  • Line: draws a line segment between two points.
  • Polyline: draws a line made of multiple line segments (polyline).
  • Fillet: draws a fillet (rounded corner) or a chamfer (straight line) between two simple Lines. introduced in version 0.19
  • Arc: draws an arc segment from center, radius, start angle and end angle.
  • Arc 3Points: draws a circular arc segment from three points that are located in the circumference. introduced in version 0.19
  • Circle: draws a circle from center and radius.
  • Ellipse: draws an ellipse from two corner points.
  • Rectangle: draws a rectangle from two corner points.
  • Polygon: draws a regular polygon from center, radius, and number of sides.
  • BSpline: draws a B-Spline from a series of points.
  • Cubic Bezier Curve: draws a Bezier curve of third degree by dragging two points. introduced in version 0.19
  • Bezier Curve: draws a Bezier curve from a series of points.
  • Point: inserts a point object.
  • Facebinder: creates a new object from selected faces on existing objects.
  • ShapeString: inserts a compound shape representing a text string at a given point.

Annotation 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.).

Obsolete

This command is considered obsolete because the Drawing Workbench is obsolete. However, the command itself is still shown in the toolbar.

These commands have been removed from the interface.

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.

Souborové formáty

Kreslicí modul poskytuje FreeCADu pro import a export následující souborové formáty:

Install importers

Přidané funkce

  • Uchopování: Umožňuje umístit nové body na zvláštní místa na existujících objektech
  • Omezování: Umožňuje umístit nové body horizontálně nebo vertikálně v relaci k předchozím bodům
  • Práce s ručními koordináty: Umožňuje vkládat koordináty ručně místo klikání po obrazovce
  • Working plane: Allows you to define a plane in the 3D space, where next operations will take place

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

Skriptování

Kreslicí modul má vlastnosti kompletního Kreslicího API, takže můžete využívat jeho funkce ve skriptech a makrech

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.
