Sketcher MapSketch

Description
This tool maps an existing sketch on the face of a shape. PartDesign features created from this sketch will be fused with the underlying solid for additive features (Pad, Revolution) or be subtracted from the underlying solid in case of subtractive features (Pocket, Groove).

Please note that this tool is not to be used to create new sketches. It only maps, or remaps an existing sketch to the face of a solid or a PartDesign feature. Typical use cases are:
 * The sketch was created on a standard plane (XY, XZ, YZ) and you want to map it to the face of a solid in order to build a feature upon it.
 * The sketch was mapped on a specific face of a solid but you need to map it to a different face.
 * Repairing a broken model.

How to use

 * Select the face of a PartDesign feature or a solid.
 * Click on the icon in the toolbar (or go to the PartDesign or Sketch menu depending on which workbench is active)
 * In the Select sketch dialog window that opens, select from the list the sketch to map to the face and click OK.
 * The sketch is automatically opened in edit mode.
