Abstract: The need for complex trusses has prompted the creation of a laser enhanced design system. Lasers mounted on the ceiling project precise images onto a gentry table below. The initial truss design is produced using a virtually any CAD system in conjunction with a work station or PC-microcomputer. A standard PC-microcomputer running MS-DOS software is used to control the laser system. The files required for the laser system are automatically created during the designing phase. The assembly line operator uses a mouse or keyboard to control and select the projected images while a worker places the truss elements over the projected images.
