Mechanic by trade (and for most of my working life, I’m 59 yo at the time of this update), now an interstate truck driver.
Enjoy fiddling around in my shed when I’m home on the weekends ( I live in the truck 5 nights a week) with small woodwork projects and found that having a plan helps which is where SU comes in.
I am pretty much clueless when it comes to any type of drawing be it 2/3D or with pencil and paper.
