STEPS FOR DRAWING PLAN

• Open auto Cad and enter UN (Units command) in the command box and select type as decimal and set precision of decimal as 0
• Select X line command and draw horizontal line and vertical line.
• Trim the unwanted lines.
• Now select offset command and give an offset of 250mm to both horizontal and vertical line drawn by X line.
• Give the offsets as follows in the X direction.
• Offset 3100 for bedrom.
• Offset 125 for internal wall.
• Offset 2250 for kitchen/ drawing room / dining room.
• Offset 125 for internal wall.
• Offset 1250 for both toilet
• Offset 250 for external wall.
• Give the offsets as follows in the X direction.
• Offset 3100 for bedroom.
• Offset 125 for internal wall.
• Offset 3225 for bedroom.
• Offset 250 for wall on both sides of stars.
• Offset 250 for treads.
• Offset 1200 for landing of staircase.
• Offset 2400 for width of staircase.
• Offset 2250 for kitchen dining bedroom.
• Offset 1000 for veranda.

DRAWING OF WINDOWS –

SIZES OF WINDOWS ASSUMED

• WI= 1000 X 1200
• W2= 1500 x 1200
• W3= 1800X 1200
• W4= 600 X 1050
• W= 1200x 1200

DRAWING OF DOORSSIZES OF DOORS ASSUMED

• D= 1200 X 2100
• DI= 750 x 2100
• D2= 900 X 2100
• 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.

RESULTS-

STEPS FOR DRAWING SECTION AA

• Select x line command and extend the lines from the plan in the downward manner to create projections.
• Offset 150mm from the ground level.
• Offset 2450 for ground floor.
• Offset 2850 for second floor.
• Offset 2850 for second floor.
• Offset 2850 for third floor.
• Offset 1000 for parapet wall.
• Offset 2500 from terrace level fo mumty.
• Offset 450 from mumty for parapet wall of mumty.
• Offset 600 and offset 1200 for O.T.H.
• For drawing of staircase offset 1250 for tread and offset 143.75 for rise 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.
• Give the dimensions by dim linear or dim continue command.
• Select the multiline text for naming of the section.

Result:

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.
• Offset 2850 for first floor.
• Offset 2850 for second floor. Offset 2850 for third floor.
• Offset 1000 for parapet wall.
• Thickness of slab is assumed to be 125 mm.
• Offset 125 rom each floor in downward manner.
• Dimensions- use dim linear or dim continuous for giving the dimensions.
• Draw the windows as desired by using the line command.

Result:

FINAL DRAWING OF PLAN ELEVATION AND SECTION COMBINED
