Here is my orthagraphic projection project of my IPad Air 2. Orthagraphic projection is used by inventors to see all the different sides of an object and to picture what it will look like in the end when they make it. I made an orthagraphic projection of my IPad and I had to take measurements and draw out all the details. Orthagraphic projection is a very useful way of picturing something and being able to see all its sides and measurements.
