Orthographic Projection

In this lesson your challenge is to create a technical drawing that measures up to professional standards. You will start by designing a 3D model of your choice and then 3D printing it as an object. You will then use a corner projection station to produce three 1st angle orthographic projections of your object. Finally, you will use these projections to produce a detailed technical drawing of your object. You can even challenge a classmate or colleague to reproduce your object from the drawing!
