Me too... I learned on drawing boards....
I took a drafting class in jr high and high school... I was at the top of my classes in drafting...
I finished all the course work two weeks early in jr high and me and the guy next to me got to do a house floor plan... He wanted to be an architect...
Then in high school I took another drafting course in freshman year and was also on the top of the class... The teacher took me and another classmate to compete in a local drafting competition here and we both came in third... The top three places got to go compete down state... However we didn't even place in the state competition, but it was a good learning opportunity... That was the first time that our teacher had students compete in state competition.... We didn't practice at all for the state competition, just went down to see what we could do...
Then I had a drafting class in college... One of our projects was to draw a scale thread... The spiral was very complicated to draw by hand accurately... But I did like the experience...
Yep, the good old drawing board, T-squares, triangles, and drafting pencils 2H and 4H....
