The purposes of the study were as follows: first, to study the literature in the field of teaching drafting with special reference to the use of instructional aides in presenting orthographic projection concerning the use of a projection box; second, to ascertain the value of the use of a tri-color projection box in teaching orthographic projection to an experimental group of students at the R. L. Turner High School, Carrollton, Texas; and third, to determine if an analysis of these data indicates a justification for the use of this type of an instructional aid in teaching orthographic projection.
