step 2:- to show the reinforcement details

• take offset command and mention a distance of 0.04
• select the line of 1 unit to be offsetted
• select the two vertical lines of length 1.6 to be offsetted
• select the two vertical lines of length 0.15 to be offsetted
• then trim the lines
• take an offset command and mention the offset distance as 0.2
• and select the top horizontal line and copy an offset up to the bottom of the structure

Q3:

Aim:- to sketch a plan of two bedroom building

step1:- to draw an outer boundary of the building as per the dimensions

• take a line command and specify the first point
• specify the next point as @4.6<0
• specify the next point as @8.8<90
• specify the next point as @4.6<180
• close the line and leave the command

step 2:- to show the partition walls

• take an offset of line 3.6 from the top
• specify the offset distance as 3.6
• take an offset of line 8.8 from the left
• specify the offset distance as 0.9
• take an offset of line 8.8 from the right
• specify the offset the distance of 1.8
• then trim the line to provide an opening
• and erase the lines

step 3:- provide steps on either side of the building

• take offset of 4.2 from the bottom
• press enter and leave the command
• take offset of 1 from the previously offset line
• trim the outer walls for providing the opening of 1 unit
• then create steps by taking an offset of 0.3 and length 1

Q4

Aim;- to sketch a crosssection of load-bearing wall showing foundation details.

step 1:- to draw a PCC bed

• take a line command
• specify the first point
• specify the next point as @0.9<0
• specify the next point as @0.45<90
• specify the next point as @0.9<180
• then close the line and click enter

step 2:- to draw a substructure

• take a line command and specify the first point at a distance of 0.15 from the face of the PCC
• specify the next point as @0.4<90
• specify the next point as @0.05<0
• specify the next point as @0.3<90
• specify the next point as @0.05<90
