An extremely useful course. Everyone in mech/aero should know how to use a 3D modeling software. The one we used was Fusion 360 and it was very intuitive. I learned it in my spare time before even entering Carleton and it took me only an hour and some youtube videos to completely master the modeling portion of this course. The descriptive geometry part is rather difficult and requires some big brain thinking though. Both Ron and the other prof were nice.
