CAD Computer-Aided-Design

CAD was invented in 1961 by Ivan Sutherland. Sutherland described a computerized Sketchpad in a doctoral thesis while attending the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. The beginnings of CAD however, can be traced to Dr. Patrick J. Hanratty who developed PRONTO in 1957, the first commercial numerical-control programming system (CAM). For that reason it is Dr. Hanratty who is most often referred to as "the father of CAD CAM".

 

CADs use computers to aid in the creation, modification of 2D or 3D model drawings of physical components. It has revolutionized modern day engineering by allowing easier development of products and product management integration. CAD can output vectors or raster graphics that can be easily edited and replicated.

​

Engineering drawing uses graphical symbols such as points, lines, notches, curves, planes and shapes.  Essentially, it gives detailed description about any component in a graphical form. A technical drawings represents a design and specifications of the physical objects. CAD enables designers to draft and develop their work digitally and archive, print and save for future editing. CADs also allow companies to create 3D samples that can be shared with different departments for approval, reducing the production lead time.

​

Examples of CAD systems include: AutoCAD, CATIA, Lectra, Gerber Accumark, Rhino, Optitex, TukaTech, Assyst, SolidWorks, Moda01, Valentina, PAD, StyleCAD, Audaces, Clo3D, Browzwear and others.

How can N-hega Technology help companies optimize their CAD use?

​

Many companies have skilled manual pattern makers and engineers that create physical templates. In order to bring these templates to a CAD system, companies must digitize their blueprints. When CAD was first introduced, companies would use manual digitizing tablets or pen digitizers to vectorize their patterns. This manual method was error prone and laborious and required that companies redraw an already designed template. In 2001, Professor Hiroshi Ishikawa (Waseda University) and Davi Geiger (NYU) founded N-hega Technology in New York City, and developed a new automatic digitizing system using image scanning techniques that would revolutionize the digitizing process.

​

The NScan Scanner and NShot Camera digitizers vectorizes images of patterns in seconds, allowing companies to focus on more creative and meaningful tasks.

 

The manufacturing and production industries are being rapidly digitized, N-hega helps companies bridge the digital transformation gap with automatic patented pattern digitizing solutions for CAD/CAM system. Scanner and Camera based digitizers were invented by N-hega Technology to aid drafters in the digitization process. If your company is in the process of adopting a new CAD software or want to accelerate their production and manufacturing process, contact us at info@n-hega.com to learn more about how we can help you increase productivity and navigate the digital transformation. N-hega systems can be introduced to any product life-cycle system since it was developed to be compatible with all CAD/CAM systems.
