See B.Des requires good proportions of drawing, and in some of the entrance you will find that you have to appear for a drawing test as well. But in general, in the professional career, there is not much of an in-hand drawing, instead most of the drawings are computer/graphics based. So if you are good in drawing then it can be a advantage for you. But if you are not that good, but you are good to qualify any entrance (in which the drawing skill required), then go for the course undoubtedly, it will not affect your career in any way.
