6. Hexagonal lamina of 25 mm side has its surface inclined at 30° to HP. Its one side is parallel to HP and inclined at 45° to VP. Draw its projections.

 

7. (a) Two points A and B are in the HP. The point A is 30 mm in front of the VP. While B is behind the VP. The distance between their projectors is 75 mm and the line joining their top views makes an angle of 45° with xy. Find the distance of the point B from the VP.

 

(b) A line AB 55 mm long makes an angle of 30° to HP and 45° to VP. The end A is 12 mm in front of VP and 15 mm above HP. Draw the projection of the line.

 

8. A hexagonal lamina of 20 mm side rests on one of its corners on the HP. The diagonal passing through this corner is inclined at 45° to HP. The lamina is then rotated through 90° such that the top view of this diagonal is perpendicular to the VP and the surface is still inclined at 45° to the HP. Draw the projections of the lamina.

 

9. A thin rectangular plate of sides 50 mm x 25 mm has its shorter side in the HP and inclined at an angle of 30° to the VP. Project its front view when its top view is a perfect square of 25 mm side.
