From FreeCAD Documentation


    In FreeCAD the word "Sketch" is normally used to refer to a Sketcher SketchObject (Sketcher::SketchObject class) that is defined by the Sketcher Workbench. This is a 2D drawing that uses mathematical constraints to describe 2D geometry precisely.

    See Sketcher SketchObject for more information about this type of object.


    There are two common ways to create a Sketch: using the Sketcher Workbench directly, or through the PartDesign Workbench.

    Sketcher Workbench

    1. Switch to the Workbench Sketcher.svg Sketcher Workbench.
    2. Press Sketcher NewSketch.svg Sketcher NewSketch.

    PartDesign Workbench

    1. Switch to the Workbench PartDesign.svg PartDesign Workbench.
    2. Press PartDesign Body.svg PartDesign Body.
    3. Press PartDesign NewSketch.svg PartDesign NewSketch.

    After you finish editing the sketch, close it to go out of edit mode. Double click on it to enter edit mode again.


    A Sketch is very commonly used in conjunction with the Workbench PartDesign.svg PartDesign Workbench to create solids by extrusion, using the PartDesign Pad.svg PartDesign Pad operation.

    Nevertheless, a Sketch can always be created by itself for any other purpose; it does not have to be tied to a PartDesign Body. For example, the Arch Window.svg Arch Window tool of the Workbench Arch.svg Arch Workbench uses Sketches to define the shapes of windows and doors; in the same way, they can be used to define the shape of Arch Wall.svg Arch Walls.
