Step 1: To draw the plan using AutoCAD 2D

Using the line, rectangle, construction lines the plan layout of a single residential building was prepared as shown.
Doors and windows was provided at places necessary as shown in plan. By providing a suitable style all the required texts was also made.
Using the DIMLIM command the dimensioning was completed.
The staircase and steps, Common corridor was made next.
Using the mirror command, the plan prepared was mirrored to obtain the ground floor of residential flat as shown.
The ground floor plan and first floor plan are prepared as shown below.

STEP 2: To project walls to convert the plan from AutoCAD 2d to AutoCAD 3D.

Now in settings select 3D Modelling and visual style control to 2D wireframe to move to AutoCAD 3D.
A copy of the residential flat was made to work with.
Turn off all layers except the wall layer.
Copy the first and second floor plan
Erase all the unwanted things such as text, dimensions etc. from the copied plan
Change the corrent layer to 3D wall layer
Take boundry command
Pick internal point
Select the internal portion of staircase
Enter
Visual style control > Shaded
Take extrude command
Extrude the Wall at 12'
It will shows the following result
Take the ucs command
Select any wall havng window
Take a rectangle command
Specify corner point > Corner of window
Specify other point > Click on opposite corner point. Enter
Move that rectangle in Z-axis at height of 3'6" to show the window seal level
Take copy command
Copy the rectangle in Zaxis at height of 5'
Extrude both the rectangles and take union command
Select the object > Wall and extruded part
Enter
Similarly by using this same process, provide the space for window as well as for doors and ventilators
Go to staircase view drawn before
Use the copy command
Copy that staircase in a building in proper way
To set the above view
Go to > Visualise tab
Click > View Manager
One dialogue box will open
Click > New
Specify View name > V1
Enter
Set current
Enter
The v1 view is saved
Use the UCS command
Copy all the respective doors and windows
Place it in a proper position
The first floor is ready
Similarly use the above methods to create 3D of the Ground floor
In 3D grund floor view, the colums are visible
Take region command
Select
Use the extrude command to show its height
From the staircase view copy the staircase and place it in a proper position
Use the flooring material to rectangle
Copy the first floor
And place it above the rectangle flooring
Take copy command and copy the first floor plan
Select object > Select the above object
Place it on the ground floor in proper manner
Rectify small errors.
