Abstract

Many personal computer based drawing programs have the capability to create a Graphics Language (GL) file for IBM and Hewlett Packard type plotters. Nearly all do not have any file output that Computer Aided Design and Manufacturing (CADAM) programs can read. This invention describes how to take a GL file and create a CADAM file.

Method to Translate a GL File to a CADAM File

Many personal computer based drawing programs have the capability to create a Graphics Language (GL) file for IBM and Hewlett Packard type plotters. Nearly all do not have any file output that Computer Aided Design and Manufacturing (CADAM) programs can read. This invention describes how to take a GL file and create a CADAM file.

The sequence of steps is: 1. Have the drawing program put the plotter output in a computer data file (versus actually plotting it). This is sometimes called a spooled output and it is the GL file itself. This can be recognized by browsing the file to see if there are GL commands like PU and PD in the file. 2. Start the utility program called DCIMPORT (part of the DESIGNCAD vendor program package from American Small Business Computers) and pick the option to convert Hewlett Packard GL files into DESIGNCAD format and run it. 3. Start the utility program called IGESOUT (again from DESIGN CAD) to create an IGES file from the newly created DESIGNCAD file. 4. Upload the IGES file to the CADAM host as an ASCII file. 5. Start the CADAM IGES processor to create the CADAM drawing file.

The only known limitations are due to the number of vectors/ lines in the original file itself. If there are too many, then CADAM will not work with the CADAM file.
