Sketcher NewSketch

Description
This will create a new sketch.

Note that the PartDesign Workbench has its own new sketch tool, when working on a PartDesign body it is preferable to use that tool.

Usage
Clicking on the icon without a face (pre-)selected will pop up a dialog asking if the sketch should be drawn on the You can change an offset to any of the three planes and the side of the offset.
 * XY-Plane
 * XZ-Plane
 * YZ-Plane

Clicking on the icon with a (pre-selected) face will cause the sketch to be mapped to the selected face.

Note
The sketch can be re-mapped to another already existing face using the Sketcher MapSketch command.

The sketch can be moved in the 3D view using Placement.
