The calculation of gripper offset has been improved when gripping around a hem. First, the new parameter Hem Flange No Grip Zone defines a length of a hem that the gripper must avoid. A gripper is allowed to partially grip on a hem (if this value is small enough). A large value will disallow gripping on the hem whatsoever. If this parameter value is larger than the hem itself, it will be ignored, allowing the gripper to postiion right up next to, but not on, the hem.

Another new parameter, Gripper Air Space Offset, augments the existing gripper shape data. This parameter defines the distance from the inside edge (as in, opposite the nose) of the gripper jaws to the backgauge. In other words, Max Gripper Offset minus Gripper Air Space Offset would give the width of the gripper "pads".
