Drafting of various geometries using Chamfer, Fillet tool in AutoCad

AIM:to draw the given sketches in auto cad.

INTIDUCTION: auto cad offfers varios toolss like rotate chamfer,move offest est to ease thr skethehing process.

PROCEDURE:

DRAWING 1:

1. open new file and set decimal and precisin to 0.00.

2.command line: fromrandom point draw 3.00m line and @2.12<45, @2.83<135 then 2.00m line and close.

3. command circle:from midpoints of 3.00m line to 1.00m and 2.40m.

4. command circle :from midpoint of 3.00m line at 2.50m and 1.00m and 0.80 at 2.50m.

5. commend erase:erose the offsets.

DRAWING 2

1.selet architural and polar tracking 15,30,45,60,and so on.

2.command line: draw a horizintal line and draw 2'6"line at 255 degrees, 3'line perpendiclar to it, 2'5" vartical line and 8' horizontal line, 1'9" vertical line and 2'10"@225 degrees and close.

DRAWING 3

1. open new fill and set engineering and precision to 0'-0.0"

2. command line 2'-6.5" in - ve X-axis, 3-3" in + ve X - axis 1-6.0" and close.

3. command circle: drow a circle of offset distance of 1'-6.0"

4. commend cirle : draw a circle of diameter of form the centre of offsetted lines

5. command erase : erase the offsets.
