This course will only teach you important command that are available to all version of autocad, because in autocad there is a lot of way to create the drawing, you can use two or more different commands and strategies but the output is still the same which is discuss on one of the video course " introduction 2 (common command and Strategy vs all command), what I want you to learn on this course is the Strategy & Techniques to produce a good drawing while using common commands. In Learning autocad commands is easy to learn but instructors that can teach you Techniques and Strategies are very rare. I am using autocad for more than five years and I am not exploring new commands and yet I can still Produce good drawings and that's what I want to share. The advantage of knowing common command that can be used in any version is when you have limited resources, for example you need to used a lower version of autocad because your computer does not meet the hardware minimum requirement of the latest version, or your company doesn't have enough budget yet to provide the latest version, but mastering the basic command and strategies will solve the problem. My advice is don't depend on advanced command.
