Creating a Layout, Section and Elevation with dimensions using AutoCad
Aim
To draw the plan, section AA and section BB of a building
Procedure
For PLAN:
Given outer wall thickness as 250mm and inner wall thickness as 125mm.
Draw XL -H and XL-V , give the thickness of wall .
Give the dimension of rooms Bedroom (3100x3100)mm by offset command.
Give inner wall dimesnion as 125mm by offset method.
Offset horizontally 2550mm ,125mm, 1250mm(toilet) ,125mm,125mm,1250mm (Toilet of C) ,3000mm ( bedroom of C),250mm (external wall)
Offset vertically 2400mm ( toilet) and 125mm ,3225mm ( bedrrom ofC) .125mm ( wall thickness).
Offset vertically 2950mm (drawing/living)from bedroom of C and give wall thickness of 125mm ,3250mm and 3200mm give wall thickness of 250mm.
Divide the rooms horizontally by offseting 3225mm,125mm,3250mm,125mm,4475mm,250mm.
Offset 2400mm vertically and 4400mm horizontally for the staircase.
Offset 3050mm vertically from drawing of C and 3225mm horizontally for the bedroom of B and offset the wall thickness also.
Offset 3300mmvertically and 3100mm horizontally for thefront bedroom.
Fillet the wall of the bedrrom with the left side wall and give wall thickness of 250mm.
Offset 100mm from the outer wall ,Draw verandah by offseting 1000mm and offset 3175mm for the bedroom of A .
Offset 2888mm for the front bedroom of A and offset wall thickness of 125mm.
Offset 1225 and 2275 mm for the toilet ,then offset 2550mm for the drwaing/kitchen/dinning of A.
Fillet all the corners and trim the excess lines.
With multiline text ,command "t"- create text box ,select standard as text style ans text height as 250mm, type the required text.
Names of rooms with sizes and marking of windows and doors.
1st, 2nd, and 3rd Floor Plan
(Scale 1:100)
For Section-AA
Assumed dimensions:
Slab thickness -100mm
Beam - 300 x350 mm
Lintel thickness - 150mm
Staircase waist slab thickness ,landing slab thickness- 100mm
Height of newel post -1000mm
Extend the wall thickness wherever the section cuts the plan.
Then draw a horizontal line to show the ground level.
Draw 150mm thickness from the ground level by offseting 150mm from ground level.
Offset a distance of 2450mm from the ground level for the ground floor height
Give slab thickness of 100mm from thr top level
Draw beams wherever the walls are there beam size of 300x350mm.
Draw columns of 400mm and 300mm width.
Draw beam of 300mm width and 270mm depth down the ground level.
At a distance 1450mm from the 300mm column draw vertical line of 143.75mm ( riser),except the top floor 143.75mm.
Draw horizontal line of 250mm.(tread)
Similary draw 8 steps , draw the landing from the 8th one and offset a thickness of 100mm downwards .(1200mm distance from the wall)
Draw an inclined line joining the riser end of the flight , offset 100mm from that line ( waist slab), then join it with the landing slab.
Mirror the steps to the opposite side meeting the next floor ,given dotted lines as it won't be visible.
Draw beam of 300x250mm as landing beam.
Give the height of newel post as 1000mm on both the start and end of flight,connect it with inclined line.
For the first floor, offset a height of 2850mm ,also give slab thickness of 100mm and beam of 300x350mm.
Extend the projected walls of 125mm and 250mm.
Extend the doors and windows from the plan to get its width , then height is given 1200mm for window and 50mm for ventilator.
Draw lintel slab of 150mm and projection of shade as 400mm.
Show section of the window on one end of wall and the stair side as it is cut by the section line
Similary copy the same in the respective floors , upto 3rd floor
On top for parapet give height of 1000mm and 2500mm for the top room.
Draw a door of 900x 2100mm door and wall thickness of 250mm on both sides.
For overhead water tank, draw a parapet height of 450mm
Extend the wall thickness and the beam
For tank, draw a line of 1200mm as height of tank and 2300mm as width of tank.
With the useof multileader text are written.
Select leader from annottae tab - multileader style manager dialogue box displays.
Create new - then give the leader points as 5 , text height as 250mm and arrow size as 1000mm.
Parapet walls are marked.
With multiline text ,command "t"- create text box ,select standard as text style ans text height as 250mm, type the required text.
Tread and riser is mentioned , Overhead water tank is marked.
FOR SECTION - BB
Project the walls and columns from the plan using line command.
Mark a vertical line showing Ground level , take offset of 150mm for P.C.C and 200mm from the ground level to show the flooring level.
Project the windows and ventilators and give the height 2100mm.
Offset slab of 100mm thickness and draw the beams.
Show the section of windows wherever the section line cuts the windows
With multileader , text size -250mm and leader point as 2 , write the text.
Command "DIMLINEAR" or from annotate toolbar select dimension-linear.
Dimension one of the room , then type command "DIMCONTINUE" , then we will be able to select the dimension continously.
If two dimension intersect each other,select break from the annotate toolbar and select the two dimension, the intersection point will have a break.
Result
Thus the given plan, section-AA,section-BB are drawn in autocad
