AIM:- To draw a geometry (polygonal shape) according to provided drawing.

INTRODUCTION:-

To draw this polygonal shape, I have used several autocad commands like- line,circle, point etc., and I set dimension (Decimal) in Autocad. Moreover, I used both rectangular coordinate system and polar coordinate system to draw various steps in this drawing. Also, I used dimesion command for measuing the dimensions in Autocad along with text command to write drawing name.

PROCEDURE:-

Open Autocad and type a command "Unit" and press enter, then set unit as decimal and set angle in degree- base angle is east -mark angle direction as anticlockwise.

Type a command "line" and provide a coorinate (2,1) then enter.
Provide the coordinate of line (@3<0)
Provide the next coordinate of line (@2.12<45) (According to Polar coordinate system calculated angle is, 180-135=45)
Provide the coordinate of line (@2.83<135)(According to Polar coordinate system calculated angle is, 180-(90/2)=135)
Provide the coordinate of line (@2<180)
Type a command close and press enter.

- Draw the perpendicular lines from the bottom intersection of both circles and through the centre to top of the circle of radius 8' and 9', which indicates the tangent points.

- Draw another circle, with center as the intersecting point of the bottom circles and with radius 41'8".
