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.

Draft objects can be used for general drafting, similar to what can be done with Inkscape or AutoCAD. But they can also form the base for the creation of 3D objects in other workbenches. A Draft Wire may define the path of an Arch Wall, a Draft Polygon can be extruded with Part Extrude, etc. Many of the Draft modifier tools can be applied to 2D and 3D objects created with other workbenches as well. You can, for example, move a Sketch or create a Draft OrthoArray from a Part object.

The Draft Workbench also provides tools to define a working plane, a grid, and a snapping system to precisely control the position of geometry.

If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, FreeCAD may not be the right choice for you. You may wish to consider a dedicated software program for technical drafting instead, such as LibreCAD or QCad.
