a) A fixed point is 75 mm from a fixed line. A point P moves such that its distance from the fixed point is twice its distance from the fixed line. Trace the locus of P. Name the curve.
b) Draw a diagonal scale of RF = 3:200 showing meters, decimeters, and centimeters and long enough to measure up to 6 meters.

The projectors drawn from the extremities of a line AB are 120 mm apart. The end A is 20 mm above the H.P. and 30 mm in front of the V.P. The end B is 80 mm above the H.P. and 70 mm behind the V.P. Determine the true length and inclinations of the line with the two reference planes.
UNIT-III
-
A regular pentagonal lamina of 30 mm side rests on one of its corners on HP. The lamina is inclined to HP such that the plan of it is an isosceles triangle with the base as 30 mm side. The side, which is opposite to the resting corner, makes an angle of 45° with VP. Draw the projections of the lamina.

A hexagonal pyramid, base 25 mm side and axis 50 mm long, has one of its triangular faces on the H.P. and the axis parallel to the V.P. Draw its projections.
UNIT-IV
-
A cylinder of 40 mm diameter and 70 mm height is resting on the H.P on its base. It is cut by a section plane perpendicular to the V.P and inclined at 45° to the H.P. The section plane is passing through a point 20 mm below the top end of the axis. Draw the sectional top view and the true shape of the section.

A cone of base diameter 50 mm and axis length 60 mm rests on its base on the H.P. A section plane perpendicular to the V.P. and inclined at 60° to the H.P. cuts the cone, bisecting the axis. Draw the development of the lateral surface of the remaining portion of the cone.
UNIT-V
