Specifying Which Elements Are in the Fence Contents

The Fence (Selection) Mode determines just what constitutes the contents of a fence — that is, whether the elements (or parts of elements) inside, outside, or overlapping the fence are "contained" by the fence to be processed.

  • Inside — Only those elements completely inside the fence are processed.
  • Overlap — Only those elements inside or overlapping the fence are processed.
  • Clip — Only elements completely inside the fence and parts of elements inside and overlapping the fence are processed.
  • Void — Only those elements completely outside the fence are processed.
  • Void-Overlap — Only those elements outside or overlapping the fence are processed.
  • Void-Clip — Only elements completely outside the fence and parts of elements outside and overlapping the fence are processed.

The Fence Selection Mode is a tool setting (labeled Fence Mode) for the fence tools in Drawing > Home > Selection > Fence Tools as well as for manipulation tools that can operate on fence contents. In the latter case, it is set with the option menu next to the Use Fence control. There is also a control in the Locks dialog.



Note: It is not necessary to place or recall a fence in order to set the Fence Selection Mode. Conversely, once a fence is placed, you can adjust the Fence Selection Mode to change the fence contents without moving or replacing the fence.
