Mapping Elements

	This task shows how to create curves or points from a sketch (as designed using the Sketcher) or from existing curves or points, onto a Sheet Metal part; and to fold/unfold it, just as other Sheet Metal elements.
	This is especially useful when: you want to generate a logotype you want to define an area for chemical milling you want to create a cutout (pocket) to solve the overlapping of walls for example (the overlapping can be checked with the Sheet Metal Production product).
	Open the Mapping1.CATPart document. These samples already contain a pre-defined sketch that will be mapped onto the part. Otherwise, you would need to defined a sketch by entering the Sketcher workbench , selecting the wall onto which the curve should lie, and drawing the sketch you wish.

	Make sure the sketch is selected, and click the`Point or Curve Mapping`icon . The Elements To Map definition dialog box is displayed, indicating which elements have been selected for mapping.

	You can manage the list of elements: to remove an element, select it from the list and use the `Clear selection` contextual menu to add an element, select it directly in the geometry. Order in the list does not matter.
	Select the `Mapping Context`, that is the element of the part on which the curve should be generated when folding or unfolding.
	The `Mapping Context` is not necessarily the support element on which the element to be mapped has been drawn. Indeed, by default, the `Mapping Context` is the last Sheet Metal feature that has been created or modified, that is the current feature in the specification tree.
	Click `OK`. The curve mapping is created and added in the specification tree.

	You can select several sketches/curves/points to be mapped at a time. Mapped curves can be created across several walls and bends.
