I've been teaching a summer course that covers 3D modeling in Rhino for the last four weeks. At the end of three weeks my students had to reverse engineer a found object, model it in Rhino and create renderings. This group of students have done extremely well in learning the various modeling techniques. I really feel like they have a strong foundation in what it takes to model something. I look forward to seeing their final projects at the end of this week; it's been a fun class and a great group of students.
