UG, proE and MASTERCAN are all our specialties and can only be used in the industrial field. Both CAD and ps design can be used, but as far as I know, the proficiency and application direction are still different from advertising design and graphic design.
According to my personal experience, the mold design is quite different from the one you like. Mold design is mainly to do process and molding design after getting the appearance of design. However, if you want to switch to other design industries now, it will be very difficult. It is very difficult for you to complete other design industries, such as advertising design, and even industrial design, because there is no professional training in the first three years, what's more, it is difficult for students in this major to find jobs now! Because you want to consider employment, other design industries will not recruit non-major students, even if you really learned a lot this year.
So I suggest you take the postgraduate entrance examination. Sometimes interest is the best teacher, but in the form of employment in China, interest can only be regarded as a hobby. You have to think about getting married and having children in the future. How much is the design? Understand what? Think about it!
As your colleague, I can only say this. It is worth encouraging to work hard for the ideal, but we should base ourselves on reality!
