Top 10 Best CAD Software for Engineers in 2021

Computer-Aided-Design software packages (CAD) have come a long way from the humble beginnings of SketchPad in 1963, which despite pioneering the creation of interactive 2D graphics on computers was tedious to operate and maintain.

Today, modern CAD software packages are feature-packed with the latest innovations in 3D and 2D design visualization formats, programming modules, and many other features.

All this enables engineers, architects, and construction personnel to take full advantage of this set-up to help them speed-up and improve upon the quality of their designs.

As competition stiffens between CAD software development companies, they are all reacting by pushing innovative boundaries to create software platforms that have a better and more responsive user interface, better collaborative features across board to foster working on the go, and many more.

In this post, we take a few minutes to explore some of the best CAD software packages in the market today, with specific emphasis on some of their stand-out features.

  1. AutoCAD

AutoCAD is a veteran in the CAD software category and the brainchild of American software manufacturer Autodesk.
