Are there any papers that compare the difficulty of learning and using Engineering software (CAD, CAE (Engineering Analysis) and CAM) with general office suite software (e.g. MSOffice software)?
Till now i don't know whether there is any thing like like. Its new subject in comparison. Actually in my view we use these tools for their some postulates an also they market their feature with the software it self. Every tool we use for same purpose have same work flow, for example the working of OrCAD and KiCAD are different at first sight but the work flow is same. i don't what kind off difficulty in it. Rather than this question you can go for some off survey along the software users.
