• 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

Trim off the extra portions at the main door

B. Creating Stairway

Change the current layer to stairs

• Draw a thread of stair line of width 3’6”
• Offset the line to distance of 10” to upwards
• Change the direction of stairs after 5 threads of stairs
• Draw another 16 threads lines of width 10” as shown in figure

C. Creating Doors and windows

Doors and windows are created as blocks and then added to the drawing

Doors

Create all door 1 using rectangles and arc of required width as shown in following figures

Convert the drawing into block using block command with name “Main_Door_4’ ”

Windows and Ventilators

Windows are created by using rectangles and offset lines from center

Top and bottom lines are draw using wall layer and rest in window layer

Step 4: Creating First 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

• As most of the plan is same for the first floor as well, such as

  • Dimensions of the main bedroom and bedroom 2 are same
  • Dimensions of stairway
  • Doorway to the balcony is similar to it draw in ground floor plan

  So all the necessary things are select and copy pasted into the first floo

Step 5: Creating Front and Side Elevations

A. Front Elevation

For obtaining the proper front elevation view from the north, vertical mirror view copy of the ground floor is created

• Change the current layer to extension lines
• Create vertical extension line at all the wall edge points
• Draw all the wall with their thick
• Each floor height is taken as 10’6”
• Trim the extra portions

 a. Doors and Windows

• Doors and windows for elevation are similar to those added in section 2-2 view
• Door of first is half visible because of the parapet wall as shown in figure
• Curved Window along the inner staircase is added at a height of 7’ from the roof bottom 

• b. First Floor Staircase

  • Staircase to the roof of the house is through the balcony in the first floor
  • Front Elevation of the staircase is side view of the stairs
  • Each step is 6” in height and 10” in length
  • First six steps are invisible because of parapet balcony wall.
  • After 11 steps flight changes direction
  • Landing is of 3’ width
  • Hand rails of height 2’9” is added to each step
  • 3 Steps are drawn at the main door

  • c.Architectural Components

    • Plants are added at the entrance on both side of main door
    • Car and Bike components are added
    • Trees are added as other components
    • Elevation Features are added on balcony walls

    d. Elevation Result

    After adding all the architectural features the result of elevation

  1. Column Layout

• Change the current layer to wall layer

  • Draw all the walls of the plan view excluding doors and windows

  Change the current layer to column layer

  • At the bottom left corner draw a rectangle using column layer
  • All the columns are of size 9”X12” or 12”X9”
  • Columns are placed along the direction of wall in some cases
  • Draw the columns at all necessary points
• Reinforcement in column consists of 6 bars of 0.472” diameter(12mm) bars
• Stirrups of side 0.315” i.e.8mm dia bars with 150mm center to center spacing

•  II. Center Line Drawing

  Change the current layer to center line

  • Draw the lines connecting centres of all columns in line
  • Both horizontal and vertical center lines are drawn
  • Give codes with alphabets for vertical center lines
  • Give code with number for horizontal center lines
  • The distance from one center line to another is to be shown

III. Footing Layout

IV. Beam layouts

i. Ground floor Beams layout

Change the current layer to beam

• Beams are drawn with dimension 9”X12” (12” is the depth of the beam)
• Beam is not used above the bathroom and puja room walls

   Hatching

  The hatching is done for all components of plan and elevation

  Elevation patterns are chosen and applied with their respective attributes

  Hatch patterns used for respective props are

  • All the walls in top view and side view are hatched with ANS132
  • All walls in front view are hatched with BRICK pattern
  • All beams and slabs are hatched with AR-CONC
  • All floors are hatched with ANS137
  • All Doors are hatched with solid colour patterns
  • All windows are hatched with gradient blue patterns

  Result:

  Residential G+1 floor design consists of plot drawing, plan view, center line drawing, column and beam layouts, elevation view and section views are drawn. The house consists of 3 bedrooms, 2 living rooms, puja room, kitchen and balcony. Layers are created in the first step and assigned accordingly. After drawing plan view one horizontal section and vertical section lines are drawn named as section 1-1 and section 2-2. Required components and furniture to the house are added using design center command and some other files are added from the cad blocks from browsing. Step by step procedure for all components is shown in respective steps.

Vastu Shastra Followed

• Entrance of the house is provided at the North-East position.
• Living room is provide at the North-West position of the house.

In the first 7 steps, all the drawings are drawn. At the end of each step, result of that step is shown. Using step 8 hatching is done for all the drawings. The final result consists of all the drawings of the residential house with hatching.

• All dimensions are in feet and inches
• Dimensions are assigned accordingly
• Text is assigned for all the required components
