What are the limitations of CAD software in mechanical design, and how can they be overcome? Provide examples of when manual drafting is still necessary in design.

CAD software has revolutionized the field of mechanical design by allowing designers to create and test complex 3D models in a digital environment. However, there are still some limitations to CAD software that can hinder the design process, and in some cases, make manual drafting necessary. One limitation of CAD software is the reliance on the accuracy of the input data. CAD models are only as accurate as the data that is used to create them. If the input data is not accurate, the resulting model will not be accurate either. This is especially true when dealing with complex surfaces, such as those found in aerodynamic designs or organic shapes. In some cases, manual drafting may be necessary to ensure that the model is accurate. Another limitation of C....
