• then change the polar tracking of OS
• polar tracking is set to 5,10, 15, 20.............
• then take a line command orient the cursor at an angle of 125
• then draw a line joining the start point

step 2:- to insert a circle of diameter 1'-6"

Q5

AIM:- to sketch a given image using the AutoCAD tools as per the required dimensions

step 1:- to create an outer line of the image

• take a line command
• specify the first point
• specify the next point as 11.5<0
• specify the next point as 6<90
• specify the next point as 11.5<180
• then click close and enter
• the other two vertical lines are drawn by taking the offset
• take offset command
• specify the offset distance as 1.5
• Click on the line to be offsetted
• and click enter

step 2:- to mark the center point of the circles

• to mark the center of the circles firstly I have drawn lines such that the intersection point is the center of the circles
• then intersection points are marked by taking nodes

step 3:- to draw circles

• take a circle command
• specify the center point
• specify the diameter as given
• then repeat the same procedure to draw other circles also

Q6

Aim:- to sketch a given image as per the given dimensions using AutoCAD tools

step 1:-to draw the first image

• firstly draw a rectangle of size 1.5 x 1.5
• then take offset command
• specify the offset distance as 0.5
• select the below horizontal line to offset
• next, select the vertical line to offset
• then click enter and leave the command
• take a command trim(TR)
• select the lines to be trimmed
• then click the space bar
• and trim the lines as per the requirement

step 2:- to draw the second image

• take a line command
• specify the first point
• specify the next point as 2<0
• specify the next point as @1.5<90
• specify the next point as @2<180
• then click close and enter
• then take offset command
• specify the offset distance as 0.5
• draw offset lines
• then take a command trim
• then select the lines to be trimmed
