I think having CAD modeling as part of the Engineering Design process is very important. Since model/prototype is one of the step in the design process, CAD modeling can be very useful and convenient in terms of making sure the ideas work out. I see myself using it quite often because I really enjoy learning and using this tool and I see myself using it when i try to design a model or just trying to see if things will work out.
CAD modeling should be used because it gives engineers a realistic view of how a model will look. Because when simply sketching a drawing and labeling the sizes can sometimes be unrealistic and will not work, and sometimes modeling can really be used to give a sense of if a model will work out, the parts that are missing, or the parts that need to be changed.
When I tried to learn how to use CAD software, I faced many obstacles. I did not have a third button mouse in the beginning so it was difficult to rotate around the model or add lengths to a size. Then small things will often stuck me such as unable to select a size, or unable to find a certain tool. But luckily, most things turn out well and smooth.
