Unit I -Plane Curves & Special Curves
Basic Geometrical constructions, Curves used in engineering practices: Conics – Construction of ellipse, parabola and hyperbola by eccentricity method – Construction of cycloid (Rolling Circle rolls on flat surface only).construction of involutes of square and circle – Drawing of tangents and normal to the above curves.

Unit II-Projection Of Points, Lines And Plane Surfaces
Orthographic projection- Principles-Principal planes-First angle projection-projection of points at First Quadrant only. Projection of straight lines (only First angle projections) inclined to both the principal planes –Determination of true lengths and true inclinations by rotating line method. Projection of planes (polygonal and circular surfaces) inclined to both the principal planes by rotating object method.

A is 35 mm above H.P. and 45 mm in front of V.P. (5)
B is 40 mm above H.P. and in V.P. (5)
C is in H.P. and 45 mm in front of V.P. (5)
D is in both H.P. and V.P. (5)
(BT-6) Create

2. A line AB 70 mm long is inclined at an angle of 300 to H.P. and 450 to V.P. The point A is 20 mm above H.P. and 15 mm in front of V.P. Draw the projections of the straight line. (BT-6) Create

3. The end A of a line AB is 10mm in front of VP and 20 mm above HP. The line is inclined at 30o to HP and front view is 45o with XY. Top view length is 60 mm long. Draw the projections. Find the true length, True and apparent inclination with VP. (BT-6) Create
