Aim: To design the given drawings in the attachment using commands in Autocad.

Introduction: By using Autocad software, we have to design the drawings given in the attachment.

Procedure: There are some drawings given in the attachment and the procedure for the drawings are listed below.

1. Procedure for the first drawing by using the units as Decimal.

First we need to take the line command and draw the line about the length of 3.0 towards X-direction.
Then from the last point take the angle of about 45deg towards 1st cordinate by using any coordinate method.
And draw the line of 2.12 distance at an angle of about 45deg.
Again take the angle of about 45deg towards negative X-direction at a distance of about 2.83
Then the angle of the two points should be 90deg.
From the last point, draw the line of about 2.0 distance towards negative X-direction.
Then join the last point and first point.
Finally mention the dimensions to each and every line and angle should be shown by using dimangle command.

2. Procedure for the second drawing by using the units as Architectural.

In this Architectural, Units should be in Feet and inches in the fraction values, But we have to take least measurement as inches.
Take the first line at a distance of 8' from the starting point.
Then from that point take 2'5" distance towards negative y-direction side.
From that point, take the rectangular coordinate method and the angle should be 45deg.
Draw the line of about 3' at an angle 45deg, and another line at an angle 45deg with distance 2'6".
Then the toal angle of the two points should be 90deg.
Now from another side of the line take the distance of about 1'9" at an angle of about 135deg.
Then by using a horizantal line, draw the line between the last 2 points.
Finally, mention the dimensions and angle of every point.

3. Procedure for the Third drawing by using the units as Engineering.

In this Engineering, Units should be in Feet and inches and least units should be taken as inches.
First we have to take the line at a distance of 2'6.5" and draw the line.
Then to the Negative Y-direction side, take the line at a distance of 3'3" and draw the line.
Now towards the positive X-direction side, draw the line at a distance of about 5'0.1".
Now again draw the line of about 1'6" distance towards Y-direction side.
Now join the first and last point of the line at an angle of about 125deg.
Again take the offset at a distance of about 1'3" to the X-direction side, and 1'6" to the Y-direction side.
Then draw the circle at a diamter of about 1'6".
Then mention all the dimensions, angle and diameter to the circle as shown in the drawing.

4. Procedure for the Fourth drawing by using the units as Decimal.

Take the line command and draw the line at a distance of about 3.0 towards X-direction as shown in the drawing.
From that take the 0.5 distance about Y-direction and again 2.5 distance to the X-direction side.
Then draw the line again to Y-direction side of about 2.5 and to the Negative X-direction side at a distance of about 2.0.
From that point again to the positive Y-direction side, draw the line of about 3.0 distance by calculating the dimensions given on the other side.
Next take the line of about 2.5 distance towards negative X-direction and draw the line.
From that point take the line of about 2.0 distance to Negative Y-direction and draw a line of about 0.5 distance by calculating the distance from the other side given.
Then draw the another line about 3.5 distance to the negative X-direction side and close te line to the first point.
Mention all the dimensions given in the drawing as shown in the attachment.

5. Procedure for the Fifth drawing by using the units as Decimal.

First take the outside line dimensions as 11.50 at X-direction side and draw the line.
Then from that point take another line of about 6.0 distance at Y-direction and draw the line.
Then draw another line of about 11.50 distance and close the line to the starting point of the line.
Now we have to draw the inside circles of the rectangle.
Take offset command and draw the line of about 1.5 distance towards X-direction side and 3.0 distance towards X-direction side.
By joining the above 2 points, take the centre point and draw the circle at a diamter of 2.0 and 1.0 from the centre points.
Draw the 2 circle on both sides of the rectangle by using same procedure.
Now, from the centre point of the circle, take the offset distance of about 4.25 from both side of the rectangle.
Again draw the circle from the centre point at a diameter of about 3.0
Now mention all the distances and diameters of the circles as shown in the drawing.

6. Procedure for the Sixth drawing.

Take the line command, and add the dimensions properly and draw the line along X-Direction at a distance of 1.5
Then take the distance as 0.5 towards Y-direction and 1.5 towards X-direction and close the line.
Now, from the one end point draw the line at a distance of 1.5 towards Y-direction.
Then draw again 1.5 towards Negative X-direction and close the line.
Now from one end take the offset distance as 0.5 and divide the line into three and close at one end.
Then with this, draw right side drawing by taking 2.0 distance in the X-direction.
Then draw the line at a distance of 1.5 towards Y-direction.
And draw at a distance of 0.5 line and close the line to the other end of the starting point.
With this drawing, again take the points and draw to the top view of the drawing by taking the points.
Or you can rotate the first drawing to the left side of the drawing.
Now mention the dimenstions to all the points as shown in the drawing.

7. Procedure for the Seventh drawing.

First take the corcle and draw the circle at a diameter of 50 and another circle at a radius of 35.
Take the centre of the circle and draw the line at a distance of 100.
From the point take another line at a distance of 210.
Now do the fillet at the corner with radius 15.
Now do the offset at a distance of 10 and 30 and 20 offset lines from the top line.
Draw the rectangle at a distance of 70 length and 30 width.
Do the mirror of the same object to the other side with the same dimensions.
Now at the bottom side of the line draw the line and do the fillet at a radius of 6.
Draw the another circle of radius 25 and another circle of diameter 30.
Take the centre point of the circles and dra the line towards Y-direction at a distance of 75.
Now give the dimensions to all the points and diameter and radius to all the circles.

8. Procedure for the Eighth drawing.

First draw the 2 circles at a diameter of 4 and at a diameter of 5.
Take the centre point of the circle and draw the reference line.
Now from the line take the distance of about 8.5 line.
Again at the both ends of the line draw the circles at a radius of 0.9 and diameter 0.9
Now join the circles using lines or arc command on both sides of the circles as shown in the drawing.
Mention all the dimension to the lines and circles.

9.Procedure for the Nineth drawing.

By using the circle with radius we have to draw this drawing.
First take the circle with radius 8' at one side and on the another side take another circle at a distance of 32'6" and radius 9'.
Now by using tan tan radius at the circle command draw another circles at a radius by subtracting the dimension from top circle radius.
Again take the circle at a radius of 41'8" and draw the circle at the center to the top of the drawing portion.
Now by using trim command trim all the unwanted portions.
Finally mention all the dimensions with radius of the circle.

10. Procedure for the Tenth drawing.

In this drawing, We have to assume our own dimensions.
Draw the rectangle with some dimension by assuming.
Do the offset to the rectangle with some distance.
Now copy the rectangle and rotate at some angle to the rectangle.
No need to mension dimensions in this drawing.

11. Procedure for the Eleventh drawing.

Take the line command and draw the line at a distance of about 20'4".
Now draw the line 4'6" and another line at 3' towards Y-direction.
Again draw the line by calculating the dimensions and draw the lines.
Now draw another line at a distance of 9' and draw another line at Negative X-direction.
Now by using coordinate method, take the angle and distance as 3'7" and draw the lines.
Angle at both sides should be 90deg as shown in the given drawing.
In the same way, by taking angle and line distance draw the same lines in the opposite side.
Now by calculating all the dimensions close the lines by using line command.
Mention all the dimensions clearly as shown in the drawing.

For all the above procedure drawings, result drawings are listed below.
