Should engineer be able to draw? Well, I suppose we deal with mechanical engineers here, because it is pretty obvious that not all engineers need to have the same skills. I woul like to tart wit a bit of history - persnal history. My latefather studied mechancal engineering inWarsaw Poland in the ae 1920's. He had wondeful drafting skils. He had to. I thin it was an important part of engineering studies then. There as simply no other way to design things.They learned caligraphy too, so tht he would be able to write understandabe notes on their drawigs. All my life envied his caligraphy. I was never even close to his hand in sketchin as simple thing as a circle. And he was excelent with ink too. When I started studying mechanical engineering I had to study drafting. It was in the early 1960's, and CAD was still far ahead. Drafting was must, but it was already more symbolic, and did not have to look as good. I knew students that switched from mechanical engineering to other faculties because they did not manage drafting. One important aspect of drafting was being able to imagin 3D from 2D and vice versa. One important skill was to sketch a given part with all dimensions, so that it will be possible to draw it later. No cellphone cameras either. Today I still do design work and I still love it. I use 3D solidworks but sometimes it happens that I am stumed on difficult dsign problem. My best strategy then is to make a local printout and use pencil to sketch on top of it. The speed and intuitivity of the pencil is an excelent tool for my mind. So yes, mechanical engineers should be able to draw!
