Some advantages of using computer aided designs include time saving, avoiding costly mistakes and improving the quality of design. The disadvantages may include costly start up expenses, elaborate training and difficulty in understanding conceptual form.
The advantages involved in CAD include:
Time saving: it takes a much shorter time to create products as compared to traditional techniques.
Prevents mistakes: some mistakes that may otherwise cost a lot of money are avoided when CAD is used.
Quality: the overall quality of the final product is considerably higher than that of one produced without CAD.
The disadvantages involved include:
Costly start up: when initially starting, factors like hardware, software and location may be required which translates into high expenses.
Training: before proper operation, elaborate training may be required in order to ensure better product quality.
