8.Command line: 2.0m horizontal and 1.5m vertical on both sides.

9. Command offset : offset 1.5m line to 0.5m

10. Command divide : divide 1.5m line into 3 segments.

DRAWING :6

1. Command rectangle : draw a rectangle of same length and some width of one smaller size and another slightly bigger one from common centre.

2. Command rotate : rotating the drawn squares by 45 degree keeping the copy.

3. Command trim : trim the crossing lines according to the fig.

DRAWING :7

1. New page set decimal and precision to 0.00.

2. Command cirde : draw concentric circles of diameter 5.00m and 4.00m.

3.Command line : from the centre point of circle draw 4.275m line on both sides.

4.Command circle : drawing a circle of diameter 0.90m on both sides.

5. Command arc : from start, end and radius draw an arc of radius 0.90 on both sides.

6.Command line : join the lines to the arc.

DRAWING : 8

1. New sheet -units- architectural-precision 0'-0"-feet- ok.

2. Limits-0'-0",0'-0" and 12'0",9'0".

3.Zoom-All.

4. Select 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 draw 3'0", 4'6",4'6",1'2". now. take copy and mirror the left to right and join to close. draw a square of side 3'0" and rotate to 45 degrees and position it using move tool. using long 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 other end.

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

1. New sheet - units decimal precision 0.0 meter ok.

2. Limits - 0,0 and 420,210.

3. Zoom -all.

4. Select line tool and draw the lengths starting from base of 210 units, now give line command @100<270. draw @75<270. draw the rectangles 70,30 and copy at distance 30.

5. draw circles with centre at Y=100 and Y=75. draw paralel lines from both the circle and using fillet tool give radius of 35,20,6 and 15.
