60 years ago, the “Father of CAD,” Dr. Patrick Hanratty created the first numerical control system, later called Computer Aided Design, which precision, versatility, and edit-ability were groudbreaking.


A CAD software is used by architects, engineers, drafters, artists, and others to create precision drawings or technical illustrations. CAD software can be used to create two-dimensional (2-D) drawings or three-dimensional (3-D) models, which can then when rotated to be viewed from any angle.

A software like this, can facilitate the manufacturing process by transferring detailed diagrams of a product’s materials processes, tolerances and dimensions or high quality  renderings, taking in account the different characteristics of every material.

The ability to digitally model and automate a prototype before ever generating a physical model adds enormous efficiency to manufacturing processes and cost reduction benefits.

In today’s industrial productions CAD technology is integrated with Computer Numerical Control (CNC) machines or Additive Manufacturing processes (3D printers) like Fused Deposition Modeling (FDM).

It is also used for highly accurate dimensional analysis and mathematical
