Abstract: One of the most important courses in engineering curriculum is “engineering drawing”. In fact, engineering drawing is the language of conversation and realization between engineers. This course consists of 3 parts: projection theory, basic drawing and mechanical drawing. The most important part between these is projection theory because it supports one of human intelligences named “spatial ability” that is vital for an engineer. Otherwise, time limits, increasing of user demands and need to higher reliability, causes us to think about “problem prevention” instead of “problem solving”. The tool helps us in this way is “failure mode and effects analysis” or FMEA. In this study, after description of FMEA elements and method of its implementation, apply it on education of projection theory in engineering drawing course and detect and analyze failure modes and effects of them, then find solutions and recommendations to prevent or weaken of these effects and finally represent result as properties of appropriate teaching of projection theory.
