2] Limits - 0,0 and 420,210
3] zoom all
4] Select line tool and draw the lengths starting from base of 1.5 units,Draw offset at 0.5.Taking the total length 1.5 draw an outer boundary and take offset of 0.5 for the vertical segments.Follow the steps to draw 2 units geometry and rotate towards left.Using line command draw the L shape geometry and connect to make the traingular portion.
5] Annotate and give dimension to all the line segments and circles.
1] New sheet - units - decimal - precision 0.00 - 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 x= 100 and y=75.Draw parallel lines from both the circle and using fillet tool give radius of 35,20,6 and 15
6] Annotate and give dimension to all the line segments and circles.
1] New sheet - units - decimal - precision 0.00 - meter - ok
2] Limits - 0,0 and 420,210
3] zoom all
4] Draw concentric circles with diameter 4 and 5 units.Draw one circle at 4.275 distance from the centre.Draw parallel line and draw a fillet of radius 0.9 and extend the lines to draw the tangent of bigger circle.Mirror the same towards right and trim the extras in geometry.
5] Annotate and give dimension to all the line segments and circles.
