草稿坊能在現有文件中快速建立平面物件，且提供數種工具用時事後修改。若干工具同時用於其他 FreeCAD 物件，不僅限於草稿坊。且提供完整 snapping system, 以及數種功能來管理物件與設定。
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.
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.

Draft annotation scale widget
With the Draft annotation scale widget the Draft annotation scale can be specified.

- Snap Intersection: snaps to the intersection of two edges.
- Snap Perpendicular: snaps to the perpendicular points on faces (introduced in version 0.21) and edges.
- Snap Extension: snaps to an imaginary line that extends beyond the endpoints of straight edges.
- Snap Parallel: snaps to an imaginary line parallel to straight edges.
- Snap Special: snaps to special points defined by the object.
- Snap Near: snaps to the nearest point on faces and edges.

Draft utility tools toolbar
- Add a new named group: creates a named Std Group and moves selected objects to that group. introduced in version 0.20
- Toggle normal/wireframe display: switches the 檢視Display Mode property of selected objects between
The Draft → Utilities menu contains several tools. Most of them can also be accessed from toolbars or the Draft Tray and have already been mentioned above. For the following tools this is not the case:
- Apply current style: applies the current style settings to selected objects.
- Layer: creates a Draft Layer. Available in the Draft utility tools toolbar in version 0.20 and below.
- Heal: heals problematic Draft objects found in very old files.
- Toggle continue mode: switches continue mode on or off.

- Snapping: select exact geometric points on, or defined by, existing objects or the grid.
- Constraining: for each subsequent point you can constrain the movement of the cursor to the X, Y, or Z direction.
- Construction mode: places new Draft objects in a dedicated group making it easier to hide or delete them.
- Pattern: Draft objects with a 資料Make Face property can display an SVG pattern instead of a solid face color.
The following additional options are available in the Tree view context menu:
For most Draft objects the following option is available:
- Edit: edits the object. Depending on the object type either Draft Edit or a dedicated edit solution is used. introduced in version 0.21
If there is an active document the context menu contains an additional sub-menu:
- Utilities: a subset of the tools available in the main Draft Utilities menu.
- Flatten: flattens the wire on the current Draft working plane. This option does not work properly in version 0.19 and below.
Layer container options
For a Draft LayerContainer these additional options are available:

- Add new layer: adds a new layer to the current document.

See also: Test Workbench.
To run the unit tests of the workbench execute the following from the operating system terminal:
freecad -t TestDraft
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:
import drafttests.draft_test_objects as dto doc = dto.create_test_file()
Inspecting the code of this module can help to understand the programming interface.
