Q9: Draw the projection of a cube of 30 mm edge resting on H.P. on one of its corners with solid diagonal vertical.

Solution:

Steps:

1. Initially assume that the cube is resting on one of its faces in H.P. such that its solid diagonal (a g or e c) is parallel to V.P.
2. Draw its top view (the top view of a cube will be a square with all sides inclined 45 with xy) . Project its front view.
3. Position the front view (inclined front view) such that its diagonal a g becomes parallel to H.P. (or xy line). Project its top view with the help of previous F.V.(3) and T.V.(1), as an initial top view(4).
4. Position the initial top view(4) such that its solid diagonal a ₂ g₂ perpendicular to V.P. This is a final top view(5).
5. With the help of the final top view(5) and initial front view(3), draw the final F.V.(6).
