  • Process for the storing of drawing data by means of a cad film-card laser plotter, a microfilm card and a cad film-card laser for its implementation
    Patent number: 5202839
    Abstract: Process for the storing of drawing data by means of a CAD film-card laser plotter, a microfilm card and a CAD film-card laser plotter for its implementation are described. A microfilm card has two film regions (2, 3), each of which is formed by a film window (4, 5) with a photographic film. Vector and/or raster data for generating an ordinary film image are stored on one film region (2), the associated CAD model data which are used by a CAD drawing system are stored on the other film region (3). In this way, the CAD model data need not be separately digitally stored. The CAD model data can be read from the film region (3) back into the CAD drawing system by means of a scanner as needed.
