What must be produced if you would like someone to build your part and define it - ANSWER- What type of view is used in engineering drawing? - ANSWER-Orthographic views. Aka multi view Why aren't pictorials enough in engineering drawings? - ANSWER-Angles not sufficiently precise. They are used as a quick representation of a part so that anyone can understand its nature. What is an orthographic? - ANSWER-Every point on the object is projected at right angles to the viewing plane (parall...
