Use this procedure to make a copy of any internal contour or hole.

1. Select either

   Edit > Copy inner contour

   or

   the Copy inner contour(s) tool

2. From there, select either to use a Rectangle or Polygon window method for performing a selection. Depending on the window method selected, the mouse pointer either changes to a rectangular selection icon () or a polygonal selection icon ().
3. Click an initial point outside of the inner contour(s) you wish to copy. Depending on the window method selected, either a rectangle (rectangular) or a single line (polygon) is rubber banded to your mouse pointer.
4. Select the next point based on the following:

   For a rectangle, select the opposite corner of the rectangular window enclosing all of the inner contours you wish to copy.

   or

   For a polygon, click the next vertex along the polygon defining the outer edge of the window are. Repeat this step until the contours you wish to copy are enclosed, double-clicking the last point to close the polygon.

5. Specify a location of the copy by either

   Clicking anywhere within the windowed area and dragging the copy to where you wish to place it. Your mouse pointer becomes a multi-arrow icon () to indicate this option.

   or

   Right-click to open the Copy of contour(s) dialog which is used to specify Y and Z offsets. Click OK to place the copy at this location.

   Copies inner contours or their vertices may not overlap with other inner contours.
