Creating a Layout, Section and Elevation with dimensions using AutoCad

AIM: Create the Plan and Sections as shown in the Figures. Use proper dimension techniques and dimension styles to document the project. Assume the sizes of the doors and windows as per construction standards. Refer to sections for stair details if required.

INTRODUCTION: Draw a section of a given floor plan by refrence of section line AA % section line BB with all details, by using auto cad 2019 and use commands like line, extend, line layer, dimension, text, hatch, offset, array, multileader & layer from layer properties. all dimension in mm (decimal)

Procedure:( For Floor Plan )

Step 1)

unit & scale setting

open the auto cad as imperical setup

set unit as Decimal and all units in mm

now set scale from directly tool bar or type SCALE in dialog box

set scale as 1:100 means 1 unit on paper is 100 unit on ground or field

Step 2)

making floor plan ( Devlopment )

choose a construction line from draw bar

draw verticle and horizontal line ( construction line )

then take offset command ( OFFSET )

and offset both construction line ( horizontal, verticle ) at a distance of 250mm as a wall thickness,

then go to horizontal axis and take offset command

and offset at a distance of 2888 for first room from last line

then offset at 125 mm as wall thickness

and then offset at 1225mm with 125mm wall thickness 125mm

angain offset at a distance of 3200mm with 125mm wall thickness

and offset at a distance of 3100mm with wall thickness 250mm as external wall thickness

now go to verticle axis and offset at 3100mm from last line with 125mm internal wall thickness

then again offset of 2550mm with 125mm wall thickness

now two times(repeat for twise) offset with 1250mm with 125mm internal wall thickness

and finnally offset with 3000mm with 250mm external wall thickness

now from top horizontal side take offsets upward on 250mm wall thickness

then from previous line take downward offset on 3225mm with 125mm wall thickness

then again offset of 2950mm with 125mm internal wall thickness

then again offset of 3050mm with 125mm internal wall thickness

then again offset of 2863mm with 125mm internal wall thickness

then again offset of 3300mm with 125mm internal wall thickness

and on bottom last room(master bed) corner make toilet of 1250X2150mm with internal wall 125mm and external wall 250mm

trim extra lines using (TRIM) command

Step 3) doors, columns, windows and staircase

provide doors and window of following dimensions

window,

W = 1400 X 1200mm

W1 = 800 X 900mm

W2 = 1000 X 1200mm

W3 = 1200 X 1200mm

W4 = 500 X 900mm

chajja 100mm projection of each side with 400mm length

&

Door

D = 1100mm

D1 = 1000mm

D2 = 900mm

Column of size 250 X 300mm

by using line command, set line from layer property and set layer with green colour draw windows according to assume size with inner panel line of 25mm thick

now, by using line command, set dash line from layer property and set layer with green colour and draw chajja with 100mm projection and 400 length

by using line command, set line from layer property and set layer with sky colour, draw colums of size 250mm X 300mm as shown in fig

then use hatch command ( HATCH )

and take solid hatch with wite colour and draw over all columns

and Trim extra lines by using TRIM command

staircase;

add layer for stair case from line property and gives yellow colour

take offset command (OFFSET) and take 250mm as a tread

and gives 8 offset of 250mm you get flight now divide it horizontally to make 2 flight

and by using multi leadre command gives direction leader to stair

step 4) naming and detailing with dimensions and also section line

Go to the text command or DTEXT set the dimensions(Scale )

and from line property gives it a colout as text line

and gives names ( text as shown in fig )

now select layer for dimension and gives it diffrent colour

then gives dimensior where it required and modify by if required

then draw section line AA and Section line BB, select line from line layer ( short dash long dash line )

and draw it as shoen in fig with diffrent colour layer

Procedure: for section AA

step1 )

choose construction line from draw command

extend all refrence line from devlope plan which are comes in section a by using verticle line

draw this all line using external line and internal line layer from layer propert (red & blue )

then take offset command OFFSET

and offset all elevation( height as per dwg )

choose line command and draw horizontal line between end verticle line

then offst it 200mm for base

then 2450mm for first floor with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 1000mm with 115mm slab thickness for parapet wall

now agin offset of 2550 with 125mm wall thickness for head room

then again 450 for parapet wall

now draw a over height water tank by offseting 1200mm from previous line

ang goves 115mm slab thickness over all tank from inner side

now by using TRIM command trim extra lines as shown in fig and make it as frame

step 2) stair case with grill and landing and window, door and beams

take ortho on

choose stair line layer command from line layer

choose a line, and go for first floor steps

draw a atep from GF line with tread- 250mm and riser- 143.75mm

then make 9 trad and 8 riser according dimension

then draw flight on front of last step with 115mm slab thick

and draw west beam for staircase by providing 250X275mm beam

and same do for next flight

now go for second floor stair

here take Tread- 250 and Riser is-158.33

draw it from first floor slab level and make 9 trad and 8 rised according to dimension

then on last line draw flight of length 1200mm with slab height 115mm

and draw west slab on bottom wich is resting on 250X275mm beam

same do for second flight wich starting from landing to second fllor

then copy the whole staircase section of FF and copy it for second and third floor

now draw stair case grill by using dash dash line layer from home tab

by choosing line command take 500mm height at every starting stair

and connect it by same layer and fillet it at junction with 5mm radius

draw samw grill overall stair section

now draw window of 1200mm height below from lintel with thick as wall thickness

draw below every flight beam with pannels of thick 20mm

create 2 opening for OHT of 1000mm width

then draw beam by using beam layer command from layer property

with depth of beam is 275mm and width is 250mm

draw all over where we cut the section and beam are visible

now same draw room windows by refrencing section lines from plans

draw it by 1200 mm depth for room window and 900mm depth for WC windows

then door

take door line layer from layer property and draw doors of 2100mm height from following refrence lines

and also draw all window projection for last wall, below the lintel with 20mm middle pannel

step3) chajja, text, dimension, GL, and leader & section line

take chajja layer property and gives it colour from layer property

and draw all chajjas of 400mm length with 1:75 slope

then by using array path command (ARRY)

first draw 1 line and acoording to that array line with path for bottom of GL as filling material

then use multileader go to setting make on proportinal schale and modify it

then draw multileder with right justify and text above the underline

and gives all specification as shown in fig using multileader

now select line layer for dimenssion

type DIM on dialog box modify setting make it text is along the line and change scale ( also from annotation )

then take linear dimension and take first base dimension then by using continue dimension and base dimension draw all the dimension

after that final stage is text

type DTEXT on dialog box go eith text setting fit scale with over all proper dimension

then using multi line text write all text required for dwg

and gives layer colour as purpol

draw section line using long dash short dash layer line from home tab

and gives it orange colour with proper proportinal scale

step 4) final section AA dwg

mearged all the stage make a final section AA dwg

Procedure for section BB:

step1 )

choose construction line from draw command

extend all refrence line from devlope plan which are comes in section a by using verticle line

draw this all line using external line and internal line layer from layer propert (red & blue )

then take offset command OFFSET

and offset all elevation( height as per dwg )

choose line command and draw horizontal line between end verticle line

then offst it 200mm for base

then 2450mm for first floor with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 2850mm with 115mm slab thickness

now again offset of 1000mm with 115mm slab thickness for parapet wall

now agin offset of 2550 with 125mm wall thickness for head room

then again 450 for parapet wall

now draw a over height water tank by offseting 1200mm from previous line

ang goves 115mm slab thickness over all tank from inner side

now by using TRIM command trim extra lines as shown in fig and make it as frame

step 2) windows, door and beams & balcony

take ortho on

draw window of 1200mm height below from lintel with thick as wall thickness

draw below every flight beam with pannels of thick 20mm

create 2 opening for OHT of 1000mm width

then draw beam by using beam layer command from layer property

with depth of beam is 275mm and width is 250mm

draw all over where we cut the section and beam are visible

now same draw room windows by refrencing section lines from plans

draw it by 1200 mm depth for room window and 900mm depth for WC windows

then door

take door line layer from layer property and draw doors of 2100mm height from following refrence lines

and also draw all window projection for last wall, below the lintel with 20mm middle pannel

draw a balcony as a refrence of plan construction line

by setting diffrent layer for it from layer property with inner gril

step3) chajja, text, dimension, GL, multi leader for text & shutter frame, parapet wall

take chajja layer property and gives it colour from layer property

and draw all chajjas of 400mm length with 1:75 slope

then by using array path command (ARRY)

first draw 1 line and acoording to that array line with path for bottom of GL as filling material

then use multileader go to setting make on proportinal schale and modify it

then draw multileder with right justify and text above the underline

and gives all specification as shown in fig using multileader

now select line layer for dimenssion

type DIM on dialog box modify setting make it text is along the line and change scale ( also from annotation )

then take linear dimension and take first base dimension then by using continue dimension and base dimension draw all the dimension

after that final stage is text

type DTEXT on dialog box go eith text setting fit scale with over all proper dimension

then using multi line text write all text required for dwg

and gives layer colour as purpol

step 4) final dwg of BB section

mearged all dwg and make final one ( by on all layer )

Result : We Draw the Plan and Sections as shown in the Figures by using edit and modify commands in auto cad with dividing various steps, we got the clear visuial and readable for easy understanding dwg during execution on site or varios purposes

following are various layer use for dwg
