Draft Workbench/cs

Introduction
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 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.

Unit tests
Test Workbench.

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

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.

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.
