CNC Center Marks

The CNC Center Marks screen configures the placement of CNC marks on member main materials to assist shop personnel in identifying the center of gravity of a member's main material, its top flange, near side, etc. These marks appear as X's on member main material in the model and on submaterial details. They may optionally be shown on member details.
