Use this procedure to remove the vertices of external or internal contours.

1. Select either

   Edit > Delete vertices

   or

   the Delete vertices tool

2. From there, select one of the following methods for vertex selection:

   Single

   or

   Rectangle

   or

   Polygon

   The mouse pointer updates to reflect the selection method.
3. Select either:

   a single vertex to delete; the mouse pointer changes to a double-line cross-hair ()

   or

   one corner of a rectangle window; the mouse pointer changes to a rectangular selection icon ()

   or

   the first vertex of a polygon window; the mouse pointer changes to a polygonal selection icon ()

   A single point selection is deleted and the shape is redrawn connecting the adjacent points. Once one or more vertices are enclosed in a completed rectangle or polygon window area, then those vertices are deleted and the adjacent vertices to those are connected.
