Sketching classes in Chicago?

I’m a recent grad in mechanical engineering and am looking to get into product design. In doing so, I would like to take a beginning sketching class for product design and was wondering if anyone had some input for classes they may know of in Chicago. I’ve looked at the Art Institute and some of the colleges in the area but haven’t seen too much offered at night or that seemed very relevant. Just curious to see if anyone out there has taken a good class in Chicago. Thanks!!

Check out and look at their education section. I believe they have some training courses related to ID in Chicago.
