This document provides instructions for drawing a staircase in AutoCAD. It describes drawing a rectangle and offsetting inner gridlines. The unnecessary lines are trimmed to create the staircase structure. Vertical offsets are drawn from the leftmost and rightmost lines using specified distances to complete the staircase drawing. Students are assigned to draw the sample staircase using their own process and document the steps. A second assignment involves drawing a column layout plan with given dimensions.

- Use the explode tool to isolate each side of the rectangle;
- Draw the inner gridlines as shown in the rightside figure using offset tool.

5. THE PROCESS OF DRAWING (CONTD.)
- Use the trim tool to erase the unnecessary horizontal as well as vertical
lines to create the staircase.
- At the last stage, draw a rightside vertical offset from the leftmost vertical
line of the rectangle (offset distance = 26.4 inch);
also draw a leftside vertical offset from the rightmost line of the rectangle
(offset distance = 13.6 inch).
- Then draw an inclined line in between these offset points to complete
drawing the staircase.
