| 109 | Methods, systems, and formats for data, such as data used in laser projection of fasteners used in manufacturing | US13230230 | 2011-09-12 | US08364438B2 | 2013-01-29 | William M. Behan; Tracy L. Bagwill |
| A system and method provides data for a laser projection process used in manufacturing involving fasteners. For example, the laser projection process may include projecting a laser image associated with fasteners used to assemble objects. Fastener attribute data may be extracted from an engineer's design data and processed to generate a laser projection output file. This output file may include geometric data used to project a laser image associated with the fasteners. For example, this image may be an outline indicating the location, shape, and orientation of a fastener. The output file may also include non-geometric data associated with attributes of the objects to be assembled. Both the geometric and the non-geometric data can then be displayed in a user interface, such as a display screen of a laser projector control device, in addition to the display of the laser image in three-dimensional space. | ||||||
