The process of digitizing, optimizing, or converting pre-existing design data—such as hand-drawn drawings, blueprints, raster pictures, or obsolete CAD files—into precise, modern CAD forms is known as CAD (Computer-Aided Design) conversion. It represents that design data can be easily modified, evaluated, and integrated into modern production and engineering processes.

The CAD conversion extend beyond simply updating the design file format. It allows for more precise modifications, detailed analysis, and the application of modern engineering standards. Once converted, the data can be used for simulations, stress testing, or creating detailed part drawings, all of which are vital for improving the functionality, efficiency, and manufacturability of the design.
