Definition of Planes

Reference planes can be created by the customer and are stored in an object named "__SBHM_PLANE_DEFINITIONS__" in the data bank connected to the environment variable SB_OGDB. Furthermore, in cases where the plane intersects the shell, a reference curve is created and stored in the data bank assigned to SB_CGDB. This is done to allow the user to mark the planes on developed shell plates as well. The curve and the plane are given the same name as defined by the user at definition (see below).

The reference planes are created from a file, containing input in TIL format. The name of this file may be selected freely.
