Section of Solids • A triangular pyramid, base 40 mm sides and axis 60 mm long, resting on its base on the HP with one of its edges parallel to the VP. A section plane passing through one of the base corners of the pyramid and the two slant edges at 20 mm and 30 mm above HP cuts the pyramid. Draw the front view, sectional top view and true shape of the section. Determine the inclination of the section plane with the reference plane. 10/25/2021 Hareesha N Gowda, DSCE, Blore-78 2
