8. Similarly take 3 units from the other side by moving cursor towards right. Then cursor downwards and draw a line of 6 units

9. Join the points on top to create a line of 5.5 units

10. Now draw a circle of 3 units in the mid point of line 11.5 units and then using move command place it in 3 units of +ve y axis.

11. Similarly draw 2 circles of 1 and 2 units and draw them in the middle point of 1.5 units below from both ends. And then move it 3 units of +ve y axis.

5. Select the Line tool and draw the lengths starting from top line segment of 9'-0", changing the position of cursor in direction of the line with ortho on.

6. Draw 3'-0", 4'-6",4'-6",1'-2". Take copy and mirror the left to right and join to close.

7. Draw a square of side 3'-0" and rotate to 45 degrees and position it using move tool. Using the line tool draw vertical lines of 2'-8" and 3'-7" and make 30 degrees line on each side with respect to reference vertical line and 60 degrees on the othe end.

5.Annotate and give dimension to all the line segments.

RESULT: The drafted geometries are done using chamfer, fillet, circle, and line tool in autocad with accurate measurement.
