This is the SECOND set of BASIC assorted shapes (there will be a total of two set of five parts) that I use in my engineering and design courses to help students develop multi-view (orthographic) and Isometric drawing skills. It also really helps them with the concept of surface identification as it relates to top, front and side views of the object. They are drawn at a large scale and in inches. So when printing scale them to a size that works for your needs. They will all print without support. I have included the STL files as well as the inventor files for your use.
