I almost went into architecture instead of engineering. I still contemplate switching over or doing architecture on the side. I think I just like design in general. You do not need a masters degree but I think you have to do some kind of appenticeship after you finish school. You don't have to be able to draw like an artist, you just need to be able to communicate your ideas on paper. You will probably have some basic drawing classes and CAD work will probably be the majority of your work so I wouldn't worry too much about freehand sketching.
