Edit Openings

An Opening is an internal hole, defined by a boundary curve having the following properties: the curve is closed, positively oriented (in a counter-clockwise direction), does not intersect any other curve or itself, and has the computational domain located on its right-hand side (in the sense of positive orientation), while the left side is not part of a computational domain. An Opening is not a part of the computational domain or surface.

An Opening can be edited using the Edit Opening dialog window, which specifies the number boundary curves defining the opening, its number, and has a box for possible comments or a description.
