1. **State the problem:** We need to design the object PQRS as a diamond shape with vertices P, Q, R, and S, inscribe a circle touching all four sides, hatch the areas between the circle and vertices P and R, type and position the text "PQRS", and plot the object on A4 paper using AutoCAD 2002. 2. **Step 1: Launch AutoCAD 2002.** Open the software to start a new drawing. 3. **Step 2: Draw the diamond shape PQRS.** - Use the LINE command to draw four lines connecting points P (top), Q (right), R (bottom), and S (left) in sequence. - Ensure the shape is a rhombus (all sides equal length) or diamond by setting equal lengths and appropriate angles (typically 45° or 90° between adjacent sides). 4. **Step 3: Inscribe the circle inside the diamond.** - Use the INSCRIBED CIRCLE command or draw a circle tangent to all four sides. - To do this, find the center point where the diagonals of the diamond intersect (this is the center of the inscribed circle). - Draw the circle with radius equal to the distance from the center to any side (perpendicular distance). 5. **Step 4: Hatch the areas between the circle and vertices P and R.** - Use the HATCH command. - Select the areas between the circle and the diamond vertices P (top) and R (bottom). - Choose an appropriate hatch pattern (e.g., ANSI31) and apply. 6. **Step 5: Type and position the text "PQRS".** - Use the TEXT command. - Position the text as indicated (usually centered inside or near the diamond). - Set the text height and font for clarity. 7. **Step 6: Plot the object on A4 paper.** - Use the PLOT command. - Set the paper size to A4. - Adjust the scale and orientation to fit the drawing properly. - Preview and print or save as required. This completes the drawing and plotting of the object PQRS as specified.
