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.
- Switch to the
Sketcher Workbench. - Press
Sketcher NewSketch.
- Switch to the
PartDesign Workbench. - Press
PartDesign Body. - Press
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 
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

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 [16px"> Arch Walls.
