Create and edit a chains and boundaries

Chains and boundaries are connected lines based on a set of segments. The main difference is that
a boundary is always closed and chains are not.

Steps

  1. Select the segments you want to add to a chain or boundary. Clicking twice on the same segment will remove the segment itself
  2. Press Enter (or right-click) to create the chain/boundary/exit editing

Remarks

  • The chains/boundary infrastructure depends highly on the topology of the curve. For example,
    you may need to click twice in parts of a closed curve that looks continuous but, since every curve
    has a beginning and an end, the two parts are different segments.
  • While selecting segments it is possible to use the undo (Ctrl + Z) function to remove the last
    selection
