6.then select offset command and enter the value of 0.5 and create the lines in vertical direction.
7. Then we specify the dimensions of the drawing.
Aim: To draw the given typical figure in autocad.
Introduction: In this we have to use fillet command for the curves between two lines.
Procedure:
1.First use line command and enter at any point.
2.Next point is (@100<90d),(@210<0d),(@75<270d).
3.Then we have create circles at the bottom enter circle command and enter point at starting point and in x direction as 35 units as given in figure.
4. then enter the diameter and enter the value of 50 diameter. and from the same point enter the circle command and enter 35 radius.

5.Enter the diamter and enter the v alue as 0.9. and from the same point create circle of radius as 0.9.
6.Then from the center of the first circle point get a distance of 4.275 in right direction.
7.Then click on enter circle command and enter diameter as 0.9 and another circle radius as 0.9 from the same point.
8.Then using line command and join the circles top and bottom.
9.Then enter fillet command and select the objects as outer circle and line in all the points.
10.Then trim the lines not required and specify the dimensions.
Aim: To draw the given drawing in autocad.
Procedure:
1.Enter the circle command and specify the any point and enter radius as 8'.
2.Then from the center of the circle using line command draw a line of 32'6".
3.Then enter circle command and specify the point at the end of line.
4.Enter the radius as 9' .
5. Then enter circle command as TAN TAN RADIUS.
6.Select the circle at the top sides of two circles and enter radius as 41'8".
7.Then we got the cirlce tangential to two circles.
8.Then enter TAN TAN RADIUS command and select the bottom of the circles and enter the radius as 20'10".
9.Then we got the circle tangential to the circles.
10.Trim the unwanted lines and specify the dimensions.
Aim: To draw the typical drawing in autocad.
Procedure:
1.enter the rectangular command and enter the values as 4X4 units to create the rectangle box.
2.Then click on offset command and enter value as 0.5 and select the objects and create another rectangle inside the rectangle.
3.Then create the same rectangles of equal sizes and enter rotate command and give the angle as 45degress and specify the point at the bottom left.
4.Then we got the required drawing.

Procedure:
1.Select line command and click at any point and enter the next point as (@3'<0d),(@4'6"<270d),(@4'6"<0d),(@1'2"<90d),(@5'4"<0d),(@1'2"<270d),(@4'6"<0d),(@4'6"<90d),(@3'<0d),(@<6'<90d).
2.Then we got the bottom part of the drawing.
3.Then for the top we have to create inclined lines as 90d and 60d.
4. For the left side from top the diatance is 2'8" and from the point draw the lines of angle 45d and 135d.
5.For the another side from the top the distance is 3'9" and from the point enter the draw the lines of angle 60d and 120d and we got the required drawing.
