Points to be borne in mind while drawing orthographic projections from pictorial views: 1. Since the pictorial view shows the object as it appears to the observer from one direction only, it may not clearly show the hidden parts, constructional details and the real shapes of its structures. All these have to be imagined before making the orthographic views 2.
