Creating a Layout, Section and Elevation with dimensions using AutoCad

Aim:- To draw the floor plans and sections using the proper dimension techniques and dimension styles to document the project.

Introduction:-

• Plan and Sections are different types of drawings used by architects to graphically represent a building design and construction.
• A plan drawing is a drawing on a horizontal plane showing a view from above.
• 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 showing what lies within.

Commands used:-
• Limits command
• Line command
• Offset command
• Hatch command
• Dimlinear command
• Dimstyle command
• Units command
• Extend command
• Fillet command
• Trim command
• Join command
• Line weight command
• Line type command
• Object snap command

Procedure:-

Step:-1
1st, 2nd, and 3rd-floor plan:
• First we have to open the AutoCAD and set the limits using the limits command.
• Next we have to draw the line with the length of 16388mm from down to up horizontally.
• Next we have to draw the line from the previous line with the length of 12150mm horizontally forwards.
• Next we have again draw the line from the previous line with the length of 16388mm downwards vertically..
• Next we have to draw the line from the last line to the first line to form the rectangle.
• Next we draw the rooms with help of line command and offset command and trim command, with the lengths given in figures.
• First we draw the bedroom with the length of 3100mm and width of 3100mm
• Next we draw the another bedroom with the size of 3225mm x 3200mm.
• Next we draw the drawing/kit/din room with the size of 2550mm x 3775mm x 3250mm.
• Next we have to draw two toilets with the sizes of 1250mm x 2400mm.
• Next we have to draw the another bed room in the part with the size of 3000mm x 3225mm.
• Next again we draw the dra/liv with the size of 4475mm x 2950mm.
• Next we draw the bedroom in the part B with the size of 3225mm x 3050mm.
we draw the dra/kit room with the size of 4475mm x 2863mm.
• Next we draw the toilet room with the size of 1250mm x 2150mm.
• Next we draw the another bedroom with the size of 3100 x 3300mm.
• Next we have to draw the balcony with a size of 1375mm x 1100mm.
• Next we draw the bedroom in the A part with the size of 3175mm x 3000mm.
• Next we leave the some space for the veranda, with a length of 3175mm.
• Next we have to draw the another bedroom with the size of 3300mm x 2888mm.
• Next we have to draw the toilet room with the size of 2275mm x 1225mm.
• Next we have to draw the dra/kit/din room with the size of 6600mm x 2550mm x 2563mm.
• Finally we draw the staircase with the size of 3200mm x 2400, the tread is 250mm and the riser is 143.75 and 158.33mm.

• Next we have to trim the unnecessary lines and objects.
• Then we draw the columns with the size of 250mm x 350mm.
• The columns are placed where ever they are required in the floor plan.
• And we specify the column layer with the sky blue color.

Next we have to draw the windows and doors with the sizes are shown below,
W1 - 900 X 1200mm
W -600 x 1200mm
W2 -1000 x 1200mm
W3 - 1500 x 1200mm
W4 - 500 x 500mm
D - 1000 X 2100mm
D1 - 700 x 2100mm
D2 -900mm x 2100mm

• Finally, we indicate the rooms using the single text command.
• And again we have to provide the dimensions for the given floor plan using the dimlinear command.
• And also draw the section lines as given in the figure, and also indicate the doors and windows.

Section-AA
• First we have to draw the line with the length of 8900mm horizontally forward.
• Next we have to draw another line from the previous line vertically with the length of 1mm.
• Next again draw the line from the previous line with the length of 11000mm horizontally backward from the previously drawn line.
• Next draw the line from the first line and the last line we drawn previously.
• Next do the offset to the particular lines with the given offset values.
• The inner wall offsets are 125mm and outer wall thickness is 250mm.
• And the ground-level thickness is 200mm and 150mm.
• Next we have to draw the windows in their requires places on the 1st, 2nd, and 3rd floors.

• Here next we have to draw the stairs with tread of 250mm and the riser with 143.75mm and 158.33mm.
• And take the line type as dashed lines and set it to the particular value of the dashed lines for the staircase.

• Next, we have to draw the remaining parts, we draw the parapet wall and water tank(O.H.T) at the top of the building.
• Next we draw the doors at their required places on the first, second, and third floors.

• Next remaining we draw the windows and sunshades in their particular places.
• Next, we have to select layers and make them to the different colors for different parts in the section, as shown below.

• Next we put the dimensions where ever they are required in the section drawing as shown below.
• Next we have to select the single text command to indicate the parts in the section plan.
• Finally we have to draw the section line in the section plan as shown in the below figure.

Step:-3
Section-BB
• First we have to draw the line with the length of 11000mm horizontally forward.
• Next we have to draw another line from the previous line vertically with the length of 16388mm
• Next again draw the line from the previous line with the length of 11000mm horizontally backward from the previously drawn line.
• Next draw the line from the first line and the last line we drew previously.
• Next do the offset to the particular lines with the given offset values.

• The inner wall offsets are 125mm and outer wall thickness is 250mm.
• And the ground-level thickness is 200mm and 150mm.
• Next we have to draw the windows in their requires places on the 1st, 2nd, and 3rd floors.

• Next, we have to draw the windows in their requires places in the 1st, 2nd, and 3rd floors.
• Next, we have to draw the sunshades in the upside of the window to protect from the sunlight.
• And we have to select the different color layers for different parts in the section plan as shown below.

• Next we have to put the dimensions where ever they are required.
• And write the text to denote the parts in the section plan using the single text command.

RESULT:-
• The 1st, 2nd and 3rd floor plan and sections using the proper dimension techniques are drawn successfully in the AutoCAD in a detailed manner.
