• Draw doors, windows and bathroom ventilators separately
• For drawing a main door
  • Draw a rectangle of size 1.2 x 2.5m
  • Draw another rectangle with offset distance 0.1m
    
    
  • 
  • Using extrude tool, make a solid element of door frame with thickness 0.15m and door with thickness 0.05m
  • Door is moved back to 0.05m
  • 
• For drawing bedroom door
  • Draw a rectangle of size 0.9 x 2.5m
  • Draw another rectangle with offset distance 0.1m
    
    
  • 
  • Using extrude tool, make a solid element of door frame with thickness 0.15m and door with thickness 0.05m
  • Door is moved back to 0.05m
    
    
  • 
• For drawing a living room window
  • Draw a rectangle of size 0.5 x 1m
  • Draw another rectangle with offset distance 0.1m
  • Divide the previous rectangle and draw two rectangles with offset distance 0.01m
    
    
  • 
  • Using extrude tool, make a solid element of window frame with thickness 0.15m, window sash with thickness 0.05m and window glass with thickness 0.01m
    
    
  • 
    
    
• For drawing a bed room window
  • Draw a rectangle of size 1 x 1m
  • Draw another rectangle with offset distance 0.1m
  • Divide the previous rectangle and draw two rectangles with offset distance 0.5m
    
    
  • 
  • Using extrude tool, make a solid element of window frame with thickness 0.15m, window sash with thickness 0.05m and window glass with thickness 0.01m
    
    
  • 
• For drawing a bathroom door
  • Draw a rectangle of size 0.7 x 2.5m
  • Draw another rectangle with offset distance 0.1m
    
    
  • 
  • Using extrude tool, make a solid element of door frame with thickness 0.15m and door with thickness 0.05m

• For drawing a bathroom ventilator
  • Draw a rectangle of size 0.3 x 0.5m
  • Draw a circle of radius 0.13m
  • 
  • Using extrude tool, make a solid element of thickness 0.15m and move the circle ie exhaust fan 0.5m towards back
    
    
  • 
• Create staircase as given in plan
• To draw a staircase
  • Draw a rectangle of size 1.23 x 2 m and divide into 2 parts
  • Draw a rectangle for landing of size 1.23 x 0.6m
  • Remaining area is divided into 7 parts with offset 0.2m (steps)
  • Regions are made in each element and using extrude tool steps and landing are raised to height of 0.25m
    
    
  • 
  • Select union and selects objects as steps
• Place all the doors, windows, staircase and bathroom ventilator according to the plan
• 
• Now create a floor at the bottom of thickness 0.1m
• Create plinth beam below with thickness 0.8m
• Create a slab at the top with thickness 0.12m (exclude the area of staircase)
• Draw walls around the opening of the staircase with wall thickness 0.15m, height 3.125m and opening of 1.53m
• Draw a door at the opening of size 1.23 width, height 3m, door frame thickness 0.15m and door thickness 0.05m
• Draw a parapet wall at the top with thickness 0.23m and height 1m
• Draw a rectangle (18 x 13m) around the residential building
• Create region of the rectangle indicating as ground level and using presspull make a thickness of 0.5m
• Assigning materials :
  • Assign materials to each solid element as given below
  • Wall and slab - Concrete
  • Floor - Wood
  • Plinth - Generic
  • Ground - Generic
  • Door frame - Wood
  • Door - Wood
  • Window sash - Plastic
  • Window frame - Wood
  • Window glass - Glass
  • Parapet wall - Brick
  • Staircase - Stone
  • Kitchen element - Stone
  • Bathroom Ventilator - Plastic and Exhaust fan - Metal
    
    
  • 
• Copy the residential building and remove slab, terrace, plinth, ground in copied building for taking pictures inside the building
• Draw a cylinder and click on create light in visualize tab
• Place point light
• Light properties are shown below
  
  
• 
• Place a camera on the edge of wall and click the images
  
  
• 
• Go to material browser in visualize tab and click on global (miscellaneous)
• Go to edit global and insert an image
• Now click on a wall near dining area and assign global to it
  
  
• 
• Now to visualize tab and click on render environment and exposure in render tab
• Switch on the environment and select image based lighting : Dry lake bed
• Now click on render to size (800 x 600 px) for rendering process and save the image
