Draft Module
Introduction
Rit modulen är ett pågående arbete och är en ganska experimentell modul som har gjorts för att lägga till grundläggande 2d ritfunktionalitet till FreeCAD. Den är helt och hållet skriven i python, och är även tänkt att fungera som en presentation om hur mycket du kan utöka FreeCAD endast med hjälp av python, utan att ens röra källkoden.
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.

The Draft Snap toolbar allows selecting the currently snapping mode. Its button keep depressed when a mode is active.
- Toggle snap: toggles object snapping globally on or off.

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.
Import & export
Detta är funktioner för att öppna, importera eller exportera andra filformat. Öppna kommet att öppna ett nytt dokument med filens innehåll, medan importera kommer att lägga till filinnehållet till det nuvarande dokumentet. Exportera kommer att spara de valda objekten till en fil. Om inget är valt, så kommer alla objekt att exporteras. Var uppmärksam på att eftersom tanken med Ritmodulen är att arbeta med 2d objekt, så fokuserar dessa importerare endast på 2d objekt, och, fastän DXF och OCA formaten stödjer objektdefinitioner i 3D rymden (objekt är inte nödvändigtvis platta), så kommer de inte att importera volymetriska objekt som nät, 3D ytor, etc, utan snarare linjer, cirklar, text eller flata former. För närvarande så stöds följande filformat:
- Autodesk .DXF: Importerar och exporterar DXF filer som har skapats med andra CAD applikationer
- SVG (som geometri): Importerar och exporterar SVG filer som har skapats med vektorbaserade ritapplikationer
- Open Cad format .OCA: Importerar och exporterar OCA/GCAD files, ett potentiellt nytt öppet CAD filformat
- Airfoil Data Format .DAT Importerar DAT filer som beskriver Vingprofiler
Install importers
- FreeCAD and DWG Import: Imports and exports DWG files
- FreeCAD and DXF Import: Imports and exports DXF files
Gemensamt beteende
