Nice CAD work. Very professional. Fabulous images of what the finished product will resemble. Boy, times, they do change.
I took two classes in engineering drafting while in college in the mid-sixties. We joked about the drafting requirements, saying that should we fail as electronics engineers, we could always find work with International Havester designing self-propelled manure spreaders.
I bought the drafting table and a super nice set of drafting instruments and used them into the early 70's for my own work and pleasure. I still pull them out on occasion, but tend to use simple Computer drafting programs for mechanical stuff and schematic programs for electronic circuit printouts. I have never considered CAD, as I can doodle out a 3-D mechanical impression and see issues develop on that front. Without free access to CAM, I always felt CAD, by itself, a bit over blown. CAD-CAM need to be fully wed and implemented together. My thoughts.
As the brain ossifies, I currently only attempt to learn that which is supremely valuable immediately which is free of any cost. As I am retired, the only new stuff I need to know is that which presents itself in the press of advancing my own personal efforts. I don't have to impress any one person or employer any more. I have a lifetime accumulation of hard won knowledge, about 60% of which is useful now only for campfire stories about how it was in the "old days". This sort of specific, focused knowledge and its application, which the young folks here strive for now, will be part of their campfire story collection in later life, as well. There will always and forever be "this new thing" leaving the bulk of your past efforts and hard won experience, a relic on the trash pile of what was once the cat's pajamas.
All that past effort in life, as you advanced, served to put bread on the table, pay for the car, etc. However, just as the bread ultimately ended up in the sewer system as consumed waste product and the car, in the junk yard, having ferried the family around so valiently, so hot, current, specific skill sets in focused endevors will also fade from being of any real value in future.
This is why I can see the sage, yet sad, Yogi Berra quote in my closing salutation as truly humorous on many levels.
Progress may have been a good thing once, but it just went on too long. - Yogi Berra
Fusion is the energy of the future....and it always will be
Retired now...Doing only what I want and not what I should...every day is a saturday.
