Challenge

Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim:

To sketch the given diagrams.

Procedure:

Draw a line of dimension 3.0 using the line command. (say ab)
Offset the line two times with a distance of 1.00 and 2.50. respectively.
With Circle command, and diameter selected, draw a circle of diameter, 0.80 from the midpoint of the offset line at 2.50 and another circle of diameter 1.00 from the midpoint of offset line at 1.
Delete the offset line using trim tool.
Using the line command, from the b point, specify the distance as 2.12 and press tab and specify the angle 45 degrees, and draw the line. ( say bc)
Using the line command, from the c point, specify the distance as 2.83 and press tab and specify the angle 135 degrees, and draw the line. ( say cd)
Now connect the point a and d using a Line.
Mark the dimensions using dimension command.

Set the units to architectural and to feets, using un command.
Draw a line of lenght 8' using line command.
From the left corner, draw another line perpenidcular, of length 2'5", and another one of length 3' at an angle of 150 degrees and atlast another one perpendicular to the previous line of length 2'9".
From the Right corner of the 8' line, draw a line perpendicular, of length 1'9" and another one of length 2'10" at an angle of 45 degrees to the previous one.
Connect the opening using line
Mark the dimensions

Draw a rectangle of dimension 5.75 length and 6 height.
From the mid point of the right edge, draw a circle of diamtere 3, using the circle command.
Select all and exploade using X command.Trim the outer semi-circle.
offset the left edge to a distance 1.5 and the bottom edge to a distance of 3.
From the interection point draw a circle of diameter 2.
Using the trim command, eliminate the unwanted lines.
Offset the previously drawn circle,inward at a distance of 1.
Select all and using the right corners as the reference, Mirror drae the whole object using MI command, and do not erase the source.
Mark the dimensions.

Draw a rectancgle of dimension dimension 1.5 (length) and 1.5 (height). Using Offset command with a offset distance 0.5, offset the bottom, left and right edge. Using trim command, erase the unwanted lines.
Draw a rectangle of dimension 2 (length) and 1.5 (height). Using Chamfer command, select distance, specify first distance as 1 and second one as 1.5, select the left and top edge to chamfer. Using offset command with a distance 0.5, offset the right and bottom edge. Using trim command, erase the unwanted lines.
Draw a rectangle of dimension 2 (length) and 1.5 (height). Using offset command with a distance 0.5, offset the right, top and bottom edge. Using trim command, erase the unwanted lines.
Mark the dimensions using dimension command.

Draw a rectangle of demsion 210 ( length ) and 100 ( height ).
Explode it.
Using offset command, Offset the left and right edge two times at distance 20 and 90. Offset the top edge two times at distance 10 and 40.
Trim the unwanted lines.
Erase the bottom edge.
From the left bottom corner Draw a line of length 70 and draw 2 circles with a diameter 70 and 50 from the mid point of the line.
Offset the top bottom at a distance downwards at a distance 70 and 75.
From the right bottom corner draw a line of length 50. Draw two circles of diameter 50 and 30 from the midpoint of the line.
Trm the unwanted lines.
Using fillet ommand and with radius 15, fillet the left and right top corner.
Fillet the line which connects the left circle at a distance 70, with radius 20.
Fillet the line which connects the right circle at a distance 70, with radius 6.
Trim the extra lines.
Mark the dimensions.

Draw a pair of concentric circle of diameter 5 and 4.
Draw another pair of concentric circle of diameter 1.8 and 0.9 at a distance 4.275 to the left from the left of mid point of the big circle.
Connect the bottom and top of the outer circles along the tangent using line command.
Mirror the sketch to the right.
Mark the dimensions.

Draw a line of length 32'-6".
Draw two circles of radius 8' and 9' from the left and right end of the line respectively.
Using Fillet tool join the two circles with radius 41'-8" at the top and 20'-10" at the down.
Mark the Dimensions.

Draw a rectangle of dimension 20'-4" (length) and 13'-6".
Offset the right and the top edge, with an offset distance 10'-2" and 6'-9" respectively.
From the intersecting point inside, draw a rectangle of dimension 3' (lenght) and 3' (height). Rotate the rectancle to an angle of 45 degrees.
Trim the unwanted lines.
Offset the top edge at a distance 9' downwards.
Offset the left and right edges at a distance 3'.
Offset the bottom edge to a distance at 1'-2".
Again Offset the left and right edge to a distance at 4'-6" .
Trim the unwanted lines.
Offset the top edge at a distance of 2'-8" and the left edge at a distance 5'-1".
From the interceting point, with polar tracking ON, draw a angle of 90 degrees.
Offset the top edge at a distance of 3'-7" and the left edge at a distance 5'-1".
From the interceting point, with polar tracking ON, draw a angle of 60 degrees.
Trim the unwanted lines.

Draw a rectangle of dimension 5'-0.1" (lenght) and 3'-3" (height).
