Draw an isometric projection of a square prism of base 40 mm side and 60 mm long axis resting on the HP such that its axis is perpendicular to HP.
ISOMETRIC PROJECTION OF SOLIDS CONTAINING ISOMETRIC LINES Example 10: Draw an isometric projection of a square prism of base 40 mm side and 60 mm long axis resting on the HP such that its axis is perpendicular to HP. It is given that the square prism is resting on its base with its axis perpendicular to HP. Hence its front view is a rectangle and its top view is a square. Draw its orthographic projections first and then draw the isometric projection. Step 1: Front view & Top view Draw top view as a square and front view as a rectangle as shown in Fig. 17.34 (i). Name the corners systematically. Step 2: Isometric projection 1. Front view is taken on the right side ie., drawn on the right isometric plane. Hence draw the isometric axes x and z. 2. Locate the point B on x axis and 1 on z axis such that AB = isometric length of a'b' and A1 = isometric length of a'1'. 3. Draw the isometric lines 1-2 and B-2 to intersect at 2. 4. Draw the isometric axis y through the origin and locate the point D such that AD = isometric length of ad. 5. Draw the isometric lines through the points D and 1 to intersect at 4. 6. Draw the isometric lines through the points 4 and 2 to intersect at 3. 7. Check the front view and top view of the isometric projection drawn and Dimension the prism properly. Example 11: In the above problem, draw the isometric projection if the prism is resting on HP on its rectangular faces with axis perpendicular to the VP. Now for the given position, front view is s a square and top view is a rectangle. Draw the orthographic projections first as shown in Fig. 17.35 (i) and then draw the isometric projection as shown in Fig. 17.35(ii). Example 12: In the above problem draw the isometric projection if the prism is resting on HP on its rectangular face with axis parallel to both VP and HP. The orthographic projections are shown in Fig. 17.36 (i) and the isometric projection is shown in Fig. 17.36(ii).
