Creating a Layout, Section and Elevation with dimensions using AutoCad

AIM: To draw the plan and sections as shown in the Figures using proper dimension techniques and dimension styles to document the project. Assuming the sizes of the doors and windows as per construction standards

Introduction:

• Plans are a set of drawings or two-dimensional diagrams used to describe a place or object, or to communicate building or fabrication instructions.
• An Elevation drawing is drawn on a vertical plane showing a vertical depiction.
• A Section drawing is also a vertical depiction, but one that cuts through space to show what lies within.
• Plan and sections are different types of drawings designed by architects and engineers to represent the building design

Commands used in this drawing:

• Limit command
• XLine command
• Line command
• Offset command
• Hatch command
• Dimlinear command
• Dimstyle command
• Units command
• Extend command
• Fillet command
• Trim command
• Circle command
• Line type command
• Layers command

Objective 1: To draw the plan of the respective drawing

Procedure:

Create a new file in AutoCAD

Type UNITS and set units to decimal with precision 0.0

Select millimeters in the insertion scale

Set current

OK

1st,2nd and 3rd floor plan:

Limit the screen from min to max by typing limit in the command prompt

Type X Line and two infinite lines are created in x and y direction

Type L and in the horizontal direction and specify the line to 12150mm

Type L and in the vertical direction and specify the line to 16388 mm

Type REC and specify a point at the last line to the first line and form a rectangle

Next draw rooms with the help on line command and offset command and trim command with the given lengths in the drawing

Draw the bedroom with the length of 3100x3100mm

For another bedroom using offset command horizontally and vertically with a distance 3225 and 3200 mm

Next draw the DRA/KIT/DIN room with size 2550 x 3775 x 3250 mm

For two toilets using offset command of distance 1250 x 2400 mm

Next draw the other bedroom in the C part of size 3000 x 3225mm

Next, DRA/LIV with the size 4475 x 2950 mm

Draw the bedroom in part B with the size 3225 x 3050 mm

Draw the DRA/KIT room with the size of 4475 x 2863 mm

Next draw the toilet room with size 1250 x 2150 mm

For another bedroom specify size 3100 x 3300 mm

Next draw the balcony with size 1375 x 1100 mm

For bedroom in A part with size 3175 x 3000 mm

Leave the horizontal distance 3175 for the veranda

Draw another Bedroom with size 3300 x 2888 mm

Draw toilet with size 2275 x 1225 mm

Next for DRA/KIT/DIN of size 6600x2550 x 2563 mm

Draw a staircase of size 3200 x 2400 with tread 250mm and riser 143.75 and 158.33 mm

Trim the extra lines and draw the doors

D

1000 X 2100 mm

D1

700 X 2100 mm

D2

900 x 2100 mm

Then draw columns of size 250 mm x 350 mm and place whereever needed in the drawing

Next Draw the windows

W1

900X 1200 mm

W

600 X 1200 mm

W2

1000 X 1200 mm

W3

1500 X 1200 mm

W4

500 X 500 mm

Place everything in respective layers

Finally we indicate the rooms using the single text command

Again provide dimensions for the given floor plan using dimlinear command

Draw the sectional lines as given in the figure and also indicate the doors and windows

RESULT:

Objective 2: To draw the section of the drawing below

PROCEDURE

SECTION-AA

Type L and specify a point and draw a line 8900 mm horizontally

Draw another line from previous line vertically with the length of 1mm

Draw the line from the previous line with the length of 11000 mm horizontally backwards

Draw the line from the first line and the last line drawn previously

Tyoe OFFSET to a particular line with the given offset values

Inner wall offset being 125mm and outer wall thickness is 250 mm

And ground level thickness is 200 mm and 150 mm

Next draw windows in their required places in 1st 2nd and 3rd floors

Draw stairs with treads of 250 mm and riser 143.75 mm and 158.33 mm

Take line type as dashed line and set it to a particular value of dashed lines for the staircase

Draw the parapet wall and water tank at top of building

Next draw doors at the required places in first second and third floors

Put them in respective layers

Finally we indicate things using the single text command

Again provide dimensions for the given floor section using dimlinear command

Draw the sectional lines as given in the figure

RESULT

Procedure

Section-BB

First draw the line with the length 11000 mm horizontally.

Next draw another line from previous line vertically with the length 16388 mm

Draw the line from the previous line with length 11000 mm horizontally backwards

Draw the line from the first line and the last line we drew previously

Do the offset to the particular lines with the offset of the given value

The inner walls are of the offset length 125mm and outer walls are of the offset 250 mm

The ground level thickness is 200 mm and 150 mm

Next draw the windows as per standards in their required places as per drawing in the 1st 2nd and 3rd floor

Select the specific elemets and put them in layers accordingly of different colours

Next we draw the windows as per standards in their required places as per drawing in the 1st 2nd and 3rd floor

Now we draw the sunshades in the upper side of the windows to protect from sunlight

Put the dimensions whereever required

Write the text to denote the sectional elevation using single line text

Change the angles of the text accordingly

RESULT

CONCLUSION:

The 1st 2nd and 3rd floor plan and sections using proper dimension techniques and dimension styles to document the project. Assuming the sizes of the doors and windows as per construction standards are drawn sucessfully

We can scale the drawings in a ratio 1:100
