My career in the drafting field is has changed over the last couple decades. My father did drafting the old way you know where you use a thing called a pencil, and something they used to write on called paper, you know the white stuff. Schools are offering classes based on CAD now and it has become the main study for the drafting field. The software is updated frequently, so drafters have to stay diverse and flexible in order to change when the programs change or incorporate new settings. Almost every field of design is involved with CAD in one way or another.
When I first started studying drafting when I was about 8 years old computers did not have programs made specifically for engineering, or architecture. My Dad had me do simple 2D designs to practice and become more skillful as a boy. When I designed these drawings I used a drafting board, mechanical pencil, ruler, compass and that was about it. Later in life while I was in High school I was introduced to a drafting course where they put away these ancient tools and traded them for computers. Luckily for everyone who has decided to become an architect or engineer CAD has changed the process of design.
