1. Click Add Layer to add multiple layers.

3. Enter the Thickness value.
4. Select the Core option.
5. Enter the Edge Setback value.
   Note: When the Edge Setback has a Negative value, the edge of the leaf will expand, rather than contract. In this case, there is no physical space for the Infill Edge leaf to appear. Thus, for "Edge Setback <= 0.0" , no Infill Edge element will be created, even if isInfill = true for that layer.
6. Enable the Infill Edge option.
7. Double click on layer in the Edge Material tab, a drop-down arrow will appear. Click on arrow and then select Family and Part.
