Kreslicí modul
The FreeCAD Draft Workbench Icon
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.
Drawing objects
These are tools for creating objects.
- Line: draws a line segment between two points.

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.).
- Move: moves objects from one location to another.

- Offset: offsets segments of an object a certain distance.
- Trim/Extend (Trimex): trims or extends an object.
- Join: joins lines together into a single wire. introduced in version 0.18
- Split: splits a wire into two at a point. introduced in version 0.18
- Upgrade: upgrades objects into a higher-level object.
- Downgrade: downgrades objects into lower-level objects.
- Scale: scales selected objects around a base point.
- Edit: edits a selected object.
- Subelement highlight: enters an edit mode that allows editing different objects. introduced in version 0.19
- Wire to BSpline: converts a wire to a B-Spline and vice-versa.
- Add point: adds a point to a wire or B-Spline.
- Delete point: deletes a point from a wire or B-Spline.
- Shape 2D View: creates a 2D object which is a flattened 2D view of a 3D object.
- Draft to Sketch: converts a Draft object to a Sketcher Workbench Sketch and vice-versa.
- Array: creates a polar or rectangular array from selected objects.
- LinkArray: creates an array of App::Link elements. introduced in version 0.19
- Polar Array: creates an array in a polar pattern, that is, sweeping an angle. introduced in version 0.19
- Circular Array: creates an array in a circular pattern, that is, starting from a center and moving outwards radially. introduced in version 0.19
- Path Array: creates an array of objects by placing the copies along a path.
- Path LinkArray: creates an array of App::Link elements by placing the copies along a path. introduced in version 0.19
- Point Array: creates an array of objects by placing the copies at certain points. introduced in version 0.18
- Clone: clones the selected objects.
- File:Draft PutOnSheet.svg Drawing: writes selected objects to a Drawing Workbench page. obsolete in version 0.17
- Mirror: mirrors the selected objects.
- Stretch: stretches the selected objects. introduced in version 0.17
Utility tools
Additional tools available from the menu Draft → Utilities, or via the right-click context menu, depending on the selected object.
- Set working plane: sets a working plane from a standard view or a selected face.
- Finish line: ends the drawing of the current Draft Wire or Draft BSpline, without closing it.
- Close line: ends the drawing of the current Draft Wire or Draft BSpline, and closes it.
