Ralph Lyle

Retired draftsman. Worked as a draftsman first for mining and then aircraft. As a draftsman I started out working with the old system of paper and pencil on a 'drafting table'. Later the computer came along and the industry adjusted to CAD, ( computer aided design ). On a main frame computer system I used Catia, ( when I was working with a company which could afford a main frame system). Later, working at a smaller company which only used personal computers, I used SodidWorks as the design software.
