Effect of computer aided drafting on manual drafting skills

Abstract

Manual drawings were the early of the evolution of drafting. With the modernization of tools like technical pens, straight edges, protractors, compasses, French curves and T-squares are generally used in manual drafting. Scientific evolution brought the innovation of computers and software like Auto-CAD that brought about Computer-Aided Drafting and Design (CADD). The tools of manual drafting are converted into commands/codes and used in modern way of drafting. These innovations made drafting faster accurate and more precise. This paper shows that what are the benefits of Computer Aided Drafting (CAD) & modern techniques are using in engineering, How to protect manual drafting skills why because to make students independent of software and on the other hand comparisons of both Computer Aided Drafting (CAD) and Manual Drafting.
