My first drafting experience was at a young age on my fathers drafting
board. While under his critical eye, I designed my first firearm, a single
shot, .22 cal. rolling block pistol. After which, I built that firearm in
the shop. By high school
mechanical drafting class many years later, I could have taught the course.
AutoCAD was a welcome and natural transition from the drafting machine and board in 1984. Version 2.17b did not yet have the trim or extend command and on an IBM 8088 machine, you could get a cup of coffee in the time a screen regen took. None the less, it was obviously the most powerful tool to hit drafting since the eraser and I never looked back. Since then, I have used every version to the current release, for over twenty years it was on a daily basis. With countless hours of experience, AutoCAD was a valuable tool to convey my ideas but I find myself using it very infrequently these days. 3D tools have advanced to the point where 2D is nearly obsolete although there are still some tasks that can be done more efficiently that way. Additionally, many customers still use it so if nothing else, it is a good platform for sharing drawings.
In 2006 I began using Inventor 8 to enhance design tasks in 3D and enjoyed it immensely. I learned Inventor the same way I learned AutoCAD... through the tutorials, books and most of all, by using it daily. I left Inventor at version 10, went to Solidworks 12 and used it up to version 18. Pro Systems (Lincoln Electric Automation) had me back on Inventor which is what I currently use daily although I am told that soon we are switching to Solidworks. Both are fine with me, they each have their own little quirks, pros and cons but I can be efficient using either one. I've had the opportunity to sample other 3D platforms over the years and have found all of them similar enough to learn quickly with the exception of Pro Engineer which seemed counter intuitive. I am confident that I could adapt to other 3D CAD programs with ease.
