Patent US 6,587,746

A code generation program, referred to as a parent program, for the creation of a child program for generating CAD script commands for automatically creating drawings in a CAD program. The parent program accepts descriptive information of the properties of various drawing entities and combines this information with computer statement templates to create functional computer statements, which calculates the values of the properties of the drawing entity. The parent program outputs these functional computer statements to the child program. The parent program also contains CAD script command templates and code to combine these templates with the calculated values of the properties of the drawing entity to create a functional CAD script command. The parent program also outputs the CAD script command templates and the CAD script combiner code to the child program.
