Projection of planes 030

  1. 1. Q12.11: A circular plate of negligible thickness and 50 mm diameter appears as an ellipse inthe front view, having its major axis 50 mm long and minor axis 30 mm long. Draw its topview when the major axis of the ellipse is horizontal.A circle can be seen as aellipse in the F.V. only when its Incline the T.V. till the Incline the F.V. till the majorsurface is inclined to VP. So for distance between the end axis becomes horizontalthe first view keep the plane // projectors is 30 mmto VP. 50 Ø 4’ 41’ 41’ 3’ 5’ 31’ 51’ 51’ 31’ 2’ 6’ 21’ 61’ 21’ 61’ 11’ 71’ 1’ 7’ 71’ 11’ 12’ 8’ 121’ 81’ 121’ 81’ 111’ 91’ 11’ 9’ 101’ 111’ 91’ X 10’ Y 11’ 101’ 121’ 21’ 30 31’ 111’ 1 2, 3, 4, 5, 6, 7 101’ 41’ 12 11 10 9 8 91’ 51’ 81’ 61’
