Orthographic Projections Test Quiz For Engineering Students

Orthographic projection is a way of representing three-dimensional things in two dimensions. It is a type of parallel projection, in which all the projection lines are orthogonal to the projection plane. It is an important topic in engineering, test your skills about this topic in this quiz!
