05 Draw concentric circles with centre @ x= 1.50 & y=3.00 of diameter 1.00 & 2.00. copy the circles toward 4.25 right from the of the rectangle.

06 Draw another circle at centre of the rectangle of diameter 3.00.

07 Annotate & give dimension to all the line segments & circles.

DRAWING-6

01 New sheet-units-decimal-precision 0.0000-meter-ok

02 Limits -0,0 & 420,210

03 Zooml-all

04 Select line tool & draw the lengths starting from base of 1.5000 units, Draw offset at 0.5000.Taking the total length 1.5000 draw on outer  boundary & take offset of 0.5000 for the vertical segments.Follow the steps to draw the L shape geometry & connect to make the triagular portion.

05 Annotate & give dimension to all the line segments & circles.

DRAWING-7

01 New sheet-units-decimal-precision 0.0000-meter-ok

02 Limits -0,0 & 420,210

03 Zooml-all

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

05 Draw circles with centre at y=100 & y=75. Draw parallel lines from both the circles & using fillet tool give radius of 35,20,6 & 15.

06 Annotate & give dimension to all the line segments & circles.

DRAWING-8

01 New sheet-units-decimal-precision 0.0000-meter-ok
