  1. All I want to do is design mechanical products using CAD software for my career. I didn't make the GPA requirement for Mechanical Engineering which contains more of the product design jobs, so I am currently an Industrial Engineering major. Will I be able to find a job with an IE degree where I can design products?.


  2. Machine selection would be more easy for the students as these are generally said to be of more importance and values and hopefully we would be able to grant more sufficient prospects. vi commands cheat sheet
