Windows are drawn by using line command.
Section lines are drawing by using layer and changing the layer type.
Hatch-For hatching the columns type hatch in command box- open settings -select pattern-select pattern as AIR-CONC-select global scale factor as 0.7.
Dimension-For drawing dimension using dimension tool in the ribbon.
Text- For naming of plan use text in ribbon in that use multiline text and keep the height of text as 220.
STEPS FOR DRAWING SECTION AA
Select x line command and extend the lines from the plan in the downward manner to create projections.

For drawing of staircase offset 1250 for tread and offset 143.75 for rse of staircase.
Offset 125 below floor level for slab.
Draw the chajjas and windows as per the sizes considered and standards.
Draw the railing of staircase in dash manner from the layers and change the layer to ACADISO03W100.
Gie the dimensions by dim linear or dim continue command.
Select the multiline text for naming of the section.
STEPS FOR DRAWING SECTION BB
Rotate the entre plan drawn earlier in the 90 degrees direction o draw the section BB.
Select x line command and take the projectors of the rotated plan in the downward manner.
Take the projections of all internal walls of 125 mm and eternal walls of 250mm. Draw a base line to draw the section BB.
Offset 150 from base line.
Offset 2450 for ground floor.
