Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim-

To draft the given diagrams using the auto cadd software

Procedure-

P1-

First start with the line command in the ribbon

start at point and staright line of length 3 units

Then with the same command direct length of length of 2.12 units and angle of 45 (@2.12<45)

Continue the straight line an give length of 2.83 units and angle of 135 (@2.83<135)

Draw the straight line of 2 units in backwards direction as shown in diagram

And close tthe polygon

Use off set command and do offset of top and bottom lines of length of 2 units in top and 1 units in bottom

The side offset line of length 1.50 units

There will be two points bisected

Make 2 points of centre of circles

Activate circle command ti ribbon with centre and radius

first circle of dia 0.80 and 1 unit

P2-

Start with line command

Start at point and length of @2'6"

Then the top line of length @8'

Then to downwards of length @1'9"

Then declined line of length and angle @2'10"<225

Come to the starting point and draw inclined line @3'<305

Then incline line of length 2'6" and angle of 90^ with reference of before line and close

P3-

Actveate line command in the ribbon

Then start at any point and draw line of length 1'6" as shown on right line

Then draw the bottom line of length of @5'0.1"

Then the next line of length3'3"

and then length of 2'6.5"

Join then in inclined lined line as shown

Offset the bottom and left line with 1'3" and 1'6"

The as centre draw circle of radius 1'6"

P4-

Invoke line command and start at any point

Draw a line of lenth of @3'

then @1'

Then @2' upwards

Thn@ @2.5'

Then @3' downwards

Then 2.5' right and

Then 2.5' downwards and join or close

P5-

Invoke rectangle tool and draw rectangle of @11.50,6

Then offset either side with length of 3 units

Then invoke circle tool and

As a centre of the each boxes draw circles

Centre corcle of diameter @3

First and last circles of dia @2 and @1

P6-

1.

Invoke rectangle command REC in command box

Then draw rec of @1.5,2 and @1.25,.5

Then oraw offsets of 0.5 either it is formed

2.

Rotate the drawing and extend 1.5 lines to 2 then the second drawing is formed

3.

Draw line of 1.5 and 2 unts length and

Offset it of 0.5

Then join edges

Then join in inclined line as triangle

P7-

Draw with line command

Line of length 100,210 and 75 lengths

Draw semicircle of radius 35 and 25 at both the ends

And join them and fillet their ends with radius of 20 and 6

Use circle command in ribbon and draw circles of radius 50 and 25 in the semicircles

Leave 20 and 10 cover on top and bottom sides

Invoke rec command

Draw rectangles on either side leaving cover of 20 for first

Rec sizes are @70,30

P8-

Activate circle command of centre and radius

Draw circle of dia 5 and offset of 1 for it

Then draw two circles of radius 0.45 on either sides

Then draw arcs of dia 0.90 on either side

then join tangent on the either side

P9-

Invoke arc and radius command

Draw top and bottom arc of radius 41'8" and 20'10"

Then close both sides with arc of radius 8' and 9' both sides

P10-

Invoke rectangle command and draw of andy size and offset it with any size

Then copy it at side and

Then use rotate command and rotate it to 45^

Fix it in the first rectangle with centre

Use trim command and trim unnecessary lines

Then it is formed

P11-

Invoke line command from ribbon

Then draw line of length @9'

Then @3'

Then @4'6"

Then @4'6"

Next is @1'2"

Then @2'7"

Then mirror the right to left as centre base

The same drawing is in right side also

Draw rectangle of @3',3'@45 whose centre is 6'9' from top

Draw inclined lines of 45^ and 60^ by angle or by reference

Of lengths 2'8" and 3'7'
