Creating a Layout, Section and Elevation with dimensions using AutoCad

[Q]: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.

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: Polygon: Rectangle: Circle: Ellipse: Offset command : Hatch command: Dimlinear command: Erase : Copy: Units command: Units command: Mirror: Extend command: Fillet command: Trim command: Array: Move : Rotate : Chamfer : Scale : Join command

Set upper limit and lower Limit Draw lines in AutoCAD Draw polygons with three or more sides Used to draw rectangles Command used to draw circles Used to draw ellipse. Used to offset one object from another a distance you specify Hatch the required area Draw the linear Dimension Manage the dimension setting Erase object in the drawing area Used to copy one or more objects Set the unit properly for the perfection of drawing Command used to mirror an exact duplicate of an object. Used to extend one line to another Sed to put a fillet between two lines of a radius you specify Command used to trim an object from another object Use to make a rectangular or polar array of an object Used to move objects around in the drawing area Used to rotate an object around a base point Used to put a chamfer between two lines Command used to make an object larger or smaller Command to join the line

• 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 klength 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 bed room 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.
• Nexr we have to draw the another bed room in the part C 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 bed room in the part B with the size of 3225mm x 3050mm.
• Next we draw the dra/kit room with the size of 4475mm x 2863mm.
• Next we draw the toilet room wwith the size of 1250mm x 2150mm.
• Next we draw the another bed room with the size of 3100 x 3300mm.
• Next we have to draw the balcony with size of 1375mm x 1100mm.
• Next we draw the bed room in the A part with the size of 3175mm x 3000mm.
• Next we leave the some space for the veranda, with the length of 3175mm.
• Next we have to draw the another bed room 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 riser is 143.75 and 158.33mm.

• Next we have to trim the unnessesary lines and objects.
• Then we draw the columns with the size of 250mm x 350mm.
• The columns are placed where ever they required in the floor plan.

• 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

• Hatching the column with concret hatch.

• Creating different layre format.

• Finally we indicate the rooms using the single text command.
• And again we have tto provide the dimrnsions 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.

Step:-2

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 horiziontally backwards from the previously drawn line.
• Next draw the line from the first line and the last line we drawn previously.
• Next do thge offset to the particular lines with the given offset values.
• The inner wall offsets are 125mm and outer wall thickness is 250mm.
• And ground level thickness is 200mm and 150mm.
• Next we have to draw the windows in their requires places in 1st, 2nd and 3rd floors.

• Draw the column as per the requirment placess.

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

• 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 in the first, second and third floors.

• Next we put the dimensions where ever they are required in the sectiion 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 a Rectangle with the length of 12050 mm Width 16388.
• The inner wall offsets are 125mm and outer wall thickness is 250mm.
• And ground level thickness is 200mm and 150mm.
• Next do the offset to the particular lines with the given offset values from the vertical line.
• 1st offset at a dist of 50 to creat the ground level line.
• Then the offset creating from that G.L line.
• Next offset dist. set as 150 from the G.L line.
• Next offset dist. set as 2450 from the Previous created line.
• Next offset dist. set as 2850 from the Previous created line.
• Next offset dist. set as 2850 from the Previous created line.
• Next offset dist. set as 2850 from the Previous created line.
• Next offset dist. set as 1000 from the Previous created line.

• Creating the Horizontal offset by using the offset command.
• 1st creating an offset distance of 250 mm from the top of the line.
• Next draw the offset at a distance of 3225 from the previous drawing offset line.
• Next draw the offset at a distance of 125 from the previous drawing offset line.
• Next draw the offset at a distance of 2950 from the previous drawing offset line.
• Next draw the offset at a distance of 125 from the previous drawing offset line.
• Next draw the offset at a distance of 3050 from the previous drawing offset line.
• Next draw the offset at a distance of 125 from the previous drawing offset line.
• Next draw the offset at a distance of 2683 from the previous drawing offset line.
• Next draw the offset at a distance of 125 from the previous drawing offset line.
• Next draw the offset at a distance of 2150 from the previous drawing offset line.
• Next draw the offset at a distance of 250 from the previous drawing offset line.
• Next draw the offset at a distance of 1150 from the previous drawing offset line.

• Next we have to draw the windows in their requires places in 1st, 2nd and 3rd floors.

• Next we have to draw the sunshades in the upside of the window to protect from the sunlight.

• 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 detailed manner.

• 1ST,2ND,3RD FLOOR PLAN

• SECTION A-A

• SECTION B-B
