Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim- To draw the geometry using decimal unit.

Commands Used-

• Line
• Dimstyle
• Units
• Offset
• Circle

Procedure-

• Select line command by typing "L" from keyboard and specify the origin of geometry (let's say 0,0)
• Specify the next point -@3,0

• specify next point - 2.5in x direction
• specify next point - 2.5in y direction
• specify the next point- 2 units in -x direction
• specify the next point - 3 units in y direction
• specify the next point - 2.5 units in -x direction
• specify the next point - 2 units in -y direction
• specify the next point - 1 unit in - x dirextion
• specify the next point - c
• press enter

Result- The geometry has been drawn.

Aim - To draw the geomery.

Commands used-

• line
• circle
• offset
• trim

Procedure- select line command from ribbon tab.

• specify the first point-(0,0)

• Specify the next point- @-11.5,0
• Specify the next point- c
• select offset command and provide offset distance 1.5,4.25,4.25 in x direction,
• using offset distance 3 in y direction we have the center of all 3 circles.
• select circle command draw the circle of diameter 1 and 2, use copy command and select the circle,
• copy it on the another center point
• repeat circle command and specify diameter of the circle as 3 at the centre of the geometry.
• using trim command trim all the unwanted lines in th geometry.

Result- the geometry is drawn using line, circle, offset and trim command.

Aim - To draw the geomery.

Commands used-

• line
• offset
• copy
• rotate

Procedure- select line command from ribbon tab.

• specify the first point-(0,0)

• select offset command
• specify offset distance .5 in y direction
• repeat offset and provide .5 offset distance in x direction.
• press enter and esc.

using copy command copy the geometry at some distance and use rotate command to rotate it.

select line command and specify the first point.

• Specify the next [email protected],0
• Specify the next point - @0,1.5
• Specify the next point- @-.5,0
• Specify the next point- @0,.1
• specify next point - @-1,0
