PROCEDURE:

Open AutoCAD

In Start-up settings start from scratch select Imperial (Feet and Inches)

Open grid and snap settings

• Change snap and grid spacing to 1’
• Change major line every grid line to 10
• Turnoff adaptive grid

Type ‘un’ in command box and press enter

Change units’ type to decimal and precision to 1’1/16” and insertion scale to inches

Step 1: Creating Layers

Open Layer properties and create new layers by clicking on new layer or right click on any layer and select new layer to create new layer

Layers are created as follows

Step 2: Creating Plot Drawing

Initially direction mark is made drawing perpendicular lines and adding text and respective layer is assigned

Change the current layer to wall layer

• Draw a rectangle of dimensions 60’X54’9.625” at any point on the screen
• Draw a line vertically up from top left corner of distance 21’
• Offset the left and bottom line of rectangle drawn to distance of 2’ right and up respectively
• Offset the top line of rectangle drawn to distance of 18’ to downwards
• Offset the right edge line of rectangle drawn to distance of 18’ to downwards
• Trim off the extra portions of inner rectangle

• Draw the roadway of width 15’ along with center alignment line
• Add relative text to the plot drawing
• Hatch the plinth area using hatch type ANS137 and hatch scale 100

Step 3: Creating Ground Floor Plan View

A. Creating Walls

Change the current layer to walls layer

• Draw a rectangle of dimensions 60’X54’9.625” at any point on the screen
• Offset the left and bottom line of rectangle drawn to distance of 2’ right and up respectively
• Offset the top line of rectangle drawn to distance of 18’ to downwards
• Offset the right edge line of rectangle drawn to distance of 18’ to downwards
• Trim off the extra portions of inner rectangle
• Offset both rectangle to a distance of 9” to inside to give the wall thickness

• Draw the inner walls of thickness 4.5”
• Offset the bottom inner wall edge to a distance of 12’
• Offset the last offset line to a distance of 4.5”
• Offset the last offset line to a distance of 4’7.5”
• Offset the last offset line to a distance of 4.5”
• Offset the left inner wall edge to a distance of 14’
• Offset the last offset line to a distance of 4.5”
• Offset the last offset line to a distance of 4.5”
• Offset the last offset line to a distance of 4’3”
• Offset the last offset line to a distance of 4.5”
• Trim off the extra lines to obtain the figure as shown below

Create the front door inside the top right corner as shown in below figure

Create the main door opening of the dimension 4’

. Drawing the plot, and giving setback.Given plot size as 18.3m x6m.Mark the direction N, S, E, W. By rectangle, draw the plot giving dimensions as 6 and 18.3 m.

3. Next give setback from the plot, 4.3m and 3m for the sides.The proposed building should come inside the setback drawn.

4. Drawing wallOffset 0.25 m from the boundary after the setback is taken for the wall thickness.

5. As the orientation is given as East, main door should face East.For living room, give 3m offset horizontally from the West side and size of the room will be 3 x 4 m.

6. As per Vaastu Shastra, North-East is favourable for living room and the entrance should face North or East.

7. Same the dining room Again offset 3m from the living wall for dining room.Width will be 4.5m

8. Offset 2m horizontally from dinning wall and 4m vertically.The size of kitchen is 2 x4 m.Trim 1 m for the door opening. According to Vaastu Shastra the ideal position for kitchen is South-East ,with cooking place facing East.

9. Drawing Master bedroom and toilet From the South wall offset 4m and width of 4m joining the kitchen wall.

10. The size of bedroom is 4x 4m.Create opening of 0.80 m by offset and trim commands.
For toilet, draw an offset horizontal of 1.5 m from the Dinining wall and Size of toilet is 1.5 x2m.

11. Drawing of Puja room From the Toilet offset 1.5m and from master bed room offset 1m and Size of the puja room is 1.5m x1.0m as per North-East should be good for puja room according to Vaastu Shastra

12. Drawing of Bed room with toilet From Living room offset 3m and from dining room offset 2.5m .Size of the bed room is 3m x 2.5m and Draw a toilet of 1.5m x 1.5m inside the bed room.

13. With multiline text, draw the text box, text height as 0.15m and style as Times roman.

14. Place the doors and windows in the respective places.

15. Elevation part the Projecting lines to draw the elevation.Project the wall lines to the top.

16. Draw a horizontal line.Offset 1 m for the plinth level.Offset 2.1m for the Lintel level.Offset 3.5m for the floor level .Offset 0.6m for the parapet wall .

17. Trim off the extension lines and make shutters and panels for doors and windows.For architectural purpose, create some hatches.

18. Project the lines from the elevation for the height and from the section line of plan for the horizontal members. Drawing windows, doors and stairs in section.

19. Using hatch hatch the walls with the bricks hatch and foundation with the concrete hatch.

20. Project the lines from the elevation for the height and from the section line of plan for the horizontal members.

21. Drawing windows, doors and stairs in section.Draw the window and door which we see after cutting the section line.

22. Using hatch hatch the walls with the bricks hatch and foundation with the concrete hatch.
Place the windows and foundations in the respective layers and give colours.

Structural drawings:

1. Column layout : Column of size 0.25m x0.25m is considered.Columns are placed in all corners of the wall and intersection of walls wherever required.

2. Now draw the centre line for column from the annotate tab -centre line and mark the grid line as 1,2 in the y direction and A, B, C, D, E, F in the x direction.

3. Footing Layout: Isolated footing of size 0.5m x0.5m is provided.Create a rectangle with dimension 0.5x0.5 m, place the centre of rectangle with the centre of column.

4. Drawing of plinth beam connect the columns by beam of width 0.25m, as the wall thickness is 0.25.Plinth beam is provided below all the walls.

5. Create a layer for beam and put the plinth beam in that layer.

RESULTS: Architectural and structural plan of a residential building is drawn
