Draw the projections of the following points on the same ground lines, keeping the projectors $15\text{ mm}$ apart: (a) A in the H.P and $40\text{ mm}$ behind V.P (b) B $45\text{ mm}$ below the H.P. and $35\text{ mm}$ behind V.P (c) C $25\text{ mm}$ above the H.P and $30\text{ mm}$ in front of V.P (d) D $50\text{ mm}$ below the H.P and $35\text{ mm}$ in front of V.P

A cone of base diameter $50\text{ mm}$ and axis $60\text{ mm}$ is resting on its base on the H.P. Draw the development of its lateral surface.

Draw the one-point perspective for a box of dimensions $(40 \times 70 \times 50)\text{ mm}$. The Station point $70\text{ mm}$ away from the picture plane and $90\text{ mm}$ above Ground. (a) SP $100\text{ mm}$ to the left of the axis (b) SP $100\text{ mm}$ to the right of the axis.

The isometric view is shown in the figure below. Draw the front view, top view and side view (looking from right). All dimensions are in mm.

Write A, B, G, I and J in Single Stroke Vertical Letter having height of 14mm.

A site plan of a road is to be prepared in which 2.5 \text{ m} of actual distance is represented by 1 \text{ m} on the drawing. Calculate the Representative Fraction (RF) of the scale and construct a diagonal scale, showing centimetres and millimetres and long enough to measure up to 20 centimetres.

On a tourist map of Mumbai, $10\text{ km}$ of actual distance is represented by $5\text{ cm}$ length on the map. What is the representative fraction of the map drawing? Draw a plain scale on the map to read up to $30\text{ km}$, and with least count of $1\text{ km}$. Show a distance of $17\text{ km}$ marked on the scale.
