After that, at the Lincoln Lab, Sutherland’s work was expanded upon by Tim Johnson who introduced three-dimensional data models and graphic images to SKETCHPAD. In 1961, Ivan Sutherland developed SKETCHPAD, universally known as the first interactive graphic system for engineering design and drafting. The history of CAD software can date back to the early 1960s. The quality of design and communication is also improved greatly. Therefore, far fewer manual efforts are needed for massive and complicated design tasks within a limited time. As its name suggests, the creation, modification, analysis, and optimization of a design can be aided by computers. ZWCAD can facilitate automotive designĬAD is short for Computer-Aided Design.

How does ZWCAD 2021 change the design workflow for the better?Īfter reading these topics, you will have a deep understanding of CAD software and how to finish the design work efficiently with ZWCAD 2021.įigure 1.In this article, a complete guide to ZWCAD 2021 will be brought out to all CAD beginners with the related topics including: ZWCAD is one of them, aiming to bring out stable and affordable CAD solutions. It turns out that more and more outstanding 2D and 3D CAD software have been springing up and growing in the past several decades. Nowadays, designers can get rid of Designers and drafters have widely accepted CAD as the benefits CAD software bring to them, encouraging a mounting number of beginners. Only after these two steps could they produce the blueprints and final drawings for construction and documentation. And then they would transfer the design on tracing papers, semi-transparent papers for exposure later, manually with a pen as well. In the old days, designers needed to finish the design on blank papers manually with a pen.
