6. command : circle, draw concentric circles at the intersection of the offset line of diameter 1.00m and 2.00m line on bothsides.
7. command:erase,the offseted lines.

DRAWING 6 :

1. New page select decimal with precision 0.0.

3. command : offset 1.5m line to 0.5m
4. Divide 1.5m line into 3 segments and join the divided line
5. Draw 2m line, 1.5m line and 0.5m horizontal at the top and in vertical and in horizontal 1.5m and vertical 0.5m and join the lines
6. Draw a line of 2m horizontal and 1.5m vertical on both sides
7. Offset 1.5m line to 0.5m
8. Divide 1.5m line into 3 segments and join the divided line
9. Trim the unwanted lines
10. Dimensions should be provided,

DRAWING 7:
