I’ve had the opportunity to give an intro to 3D design class several times now and each time I learn a little more. I am also surprised at how interest keeps building in the service. I have started surveying the folks who come to the classes to try to get an idea of where to grow the program. The last survey was pretty unanimous in that participants want more advanced training with CAD software. I used an old advertising trick that doctors hate to get them to fill out the surveys, I offered one free print to whomever completed a 5 question Survey Monkey questionnaire.
