A thin rectangular plate with dimensions 60 mm x 30 mm has its shorter side along the vertical plane and inclined at 30 degrees to the horizontal plane. Its top view can be projected by first drawing its front view as a 30 mm square. The front view is then inclined at 30 degrees to the horizontal plane to project the top view.

1. Q12.10: A thin rectangular plate of sides 60 mm X 30 mm has its shorter side in the V.P. and inclined at
30º to the H.P. Project its top view if its front view is a square of 30 mm long sides
A rectangle can be seen as a square F.V. (square) is drawn first Incline a1’b1’ at 30º to the H.P.
in the F.V. only when its surface is
inclined to VP. So for the first view
keep the plane // to VP & shorter
