Introduction

The programming advancement in the current era has been utilized on a larger scale by various professionals. There has been a dramatic swipe up and replacement of human resources by artificial intelligence in every field. Coming to a point, here in this article, we are going to elaborate on some basic information about the CAD programme, its purpose, and what exactly it is all about.

What is CAD software- an overview

CAD, known as computer-aided design and drafting- CADD is the technology for design and technical documentation, replacing manual drafting with an automated process. If you are a professional designer, drafter, architect, or engineer, you have probably used 2D or 3D CAD programs such as AutoCAD and AutoCAD LT software. These widely used software programs can help one with draft construction documentation, explore 2D and 3D design ideas, visualize various concepts through photorealistic renderings and simulate how a design performs in the real world.

What does a CAD program do?

The CAD programme is used by engineers, architects, and construction managers, and CAD has replaced manual drafting. It helps users create designs in either 2D or 3D to visualize the construction. CAD programme¬†enables the design process’s development, modification, and optimization.

History of CAD programme 

The origins of the CAD programme trace back to the early 60s and Patrick Hanratty and Ivan Sutherland. While functioning for General Electric, Hanratty developed a DAC program, the first system that used interactive graphics and a numerical control programming system. Just about a couple of years later, in 1963, Ivan Sutherland designed a system that “broke new ground in 3D computer modeling and visual stimulation, which is the basis for CAD.” Sutherland called this program Sketchpad and explained it “let designers use a light pen to create engineering drawings directly on a CRT.”

In 1971, the famous Hanratty developed a program called ADAM. It was described earlier as the “first commercially available integrated, interactive graphics design, drafting, and manufacturing system.” Approximately nine in 10 CAD programs find their roots in ADAM.

Hanratty upgraded ADAM over time, enabling it to run on 16-bit and later 32-bit computers. With a name change to AD-2000 and more machining and surfacing capabilities, the program became a hit.

Purpose of CAD 

Used by engineers, architects, and construction managers, CAD has replaced manual drafting. It helps users create designs in either 2D or 3D to visualize the construction.
