Overall it is clear to see that CAD
drawings have enabled the manufacturing process to evolve with technological
advancements. CAD offers many benefits as discussed above which further
increase operational scope. However this is all dependant on the investment
companies are willing to make into both software,hardware and peopleware. Without
these investments the ability to manufacture efficiently and with greater
accuracy will be hindered. This can see competitors increase their scale and
gain greater market share. It is vital that drawings created comply with

drawings. This will further enhance the company’s ability to communicate and
outsource.

 

Some features of modern CAD systems
