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.

  1. 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. 
  1. 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.
  1. 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.
