Project 2_Creating a 3D rendered model for a Residential Building in AutoCad

1.AIM;-TO create a 3D rendered model for a residential building with the use of AutoCAD 2022

INTRODUCTION:- 3D models are of following three types:-

a) Wireframe model:- It is basically drawn with the lines.

b) Surface model:- It is basically created of various lines to join

c) Solid models:-It is a model which is having mass

Rendering is a process in which gives realistic process of the products. It starts with the 3D modelling.

The followning dimensions have been provided for residential building which is given below:-

a) Kitchen Room ( 1.96 m* 2.43 m)

b) Bedroom ( 2.43 m*2.48 m)

c) Dining room (2.89 m*3.41 m)

d) Toilet 2 Nos ( 1.38 m*1.09 m)

e) Dining Room (2.89 m*3.41 m)

f) Living Room ( 1.96 m*2.58 m)

g)Bedroom (2.43 m* 2.58 m)

PROCEDURE:-

• Open the AutoCAD 2022 Application Software
• Type a command QNEW to save the application file
• Type a  command UNITS

• Select 3D modelling switch options
• Select top view of the cubic section
• Draw the plan of building as per  specifications provided in the given drawing
• Select the 3D view cube space
• Type a command LA

• Type a command BO
• Pick internal points
• Select the region and press Enter
• Type a command extrude. Specify the object
• Select extrude of specific height along z axis:- 3000 
• For wall type a boundary of wall of specific height 1000
• For ventilation type a boundary wall of specific height 600
• For plinth beam extrude the bottom layer to a specific height -600
• For ground floor extrude the bottom layer to a specific height 100
• Select the boundary layer and give it specific region
• For parapet wall extrude the top most layer to a height of 600
• For top floor extrude it a height of 150

• For steps extrude it to a specific height of 150 mm for 1000 mm length
• Type a  UCS command  and then select the axis for extruding the object along specific plane
• Draw a door in 3D by typing a command EXTRUDE to a particular height 2000
• For window type a command BO
• Pick an internal point
• Select the particular region for window frame
• Type a command SUBTRACT to subtract the bigger object from the smaller one
• For window mullion type a command BO
• Pick an internal point and then select the particular region 
• Type  a command Subtract select the bigger region and then subtract the bigger region from the smaller one
• Foe window glass define the layer by a specific colour. Type a command BO 
• Pick an internal point  and then select the particular region
• Type a command Subtract to subtract the bigger object from the smaller one
• Selct the window frame and then extrude it to a particular height 75 mm
• Select the window glass and then extrude it to a particular height say 12 mm
• Select the mullion and then move it to a specific distance say 12 to 15 mm
• Slect the window object and move it to a specific destination
• For creating a doors type a command BO
• Pick an internal point  and then allowed it to a particular object say 75 mm for door frame and then again extrude the object to 25 mm
• For camera view create a cylinder and then extrude it for 1500 mm
• Specify the camera location and named the camera say cam1
• Specify the camera height 1500
• Specify lens length 30 mm
• Saved it in view manager cam1

• Set the light. The visualise>Create light>Distant Light. Allow the distant light to set
• For material browser  type a command RMAT and select it as per user preferences
• For selecting an object type a command SETUV mapped the object and then assign the material by using material browser collection
• Go for visualise> Render>Render Environment and Exposure>Render On>Select image based lightning
• Again go to rendering option>select the size . Type RR for rendering
• Save the render as jpg or png file

RESULT:- 3D model of residential building have been drawn along with rendering with the use of AutoCAD 2022
