1. Q12.11: A circular plate of negligible thickness and 50 mm diameter appears as an ellipse in
the front view, having its major axis 50 mm long and minor axis 30 mm long. Draw its top
view when the major axis of the ellipse is horizontal.
A circle can be seen as a
ellipse in the F.V. only when its Incline the T.V. till the Incline the F.V. till the major
surface is inclined to VP. So for distance between the end axis becomes horizontal
the first view keep the plane // projectors is 30 mm
to VP.
