If we are Clipping a Fence (Clip or Void-Clip) then the clipped elements are always closed elements. For example, if a circle is clipped then the result is a complex shape not an arc.
I think the "Fence Mode" should have more options:
- Inside
-Overlap
-Clip (generate closed elements)
-Clip (without closed elements)
- Void.
-Void-Overlap
-Void- Clip (generate closed elements)
-Void-Clip (without closed elements)
