Answer» CORRECT choice is (c) visual ray Explanation: In the visual ray method,the points on the perspective are obtained by project ting the top view with either the front view or the side view of the visual rays. The method of drawing the perspective by visual ray method is illustrated by the PROBLEM below: Problem A hexagonal lamina of 45 mm edge LIES on the ground.The corner which is nearest to PPP is 25 mm behind it and anedge containing that corner is making 50° to PP. The station point is 50 mm in front ofPPP. 60 mm above Ground plane and lines in a CENTRAL plane which is80 mm to the left of the corner nearest to PPP. Draw the perspective view of the lamina by visual ray method. Solution: The solution to the problem is illustrated in figure below:- |
