AIM : To create various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad

INTRODUCTION :

• Open autocad application
• Type Qnew and open new drawing
• Set units according to drawing
• Switch ON 3D modeling in work space switching
• Switch on 2D object snap and 3D object snap modes
• Ortho mode is ON

PROBLEM 1 :

AIM : To create 3D furniture element using AutoCad

PROCEDURE :

• Set units to engineering
• Set units in dimensions to engineering
• Take XY plane , draw three rectangles of size 2" x 2', 3' x 2", 2" x 2' as shown below
  
  
• 
• Using region tool and boundary tool, create a region in these 3 rectangles
• Now enter extrude in command
• Select the objects and enter the height 2'6"
• Create a rectangle at the top of the object and convert into a region
  
  
• 
• In the ZX plane create a rectangle of size 3' x 2" at the top as shown below and covert that rectangle also into region
  
  
• 
  
  
• Set the origin to draw the dimensions
• Using dimlinear dimensions are drawn

RESULT :

3D Furniture element is created and it is shown in shaded view

PROBLEM 2 :

AIM : To create 3D model of isolated footing

PROCEDURE :

• Set units to engineering
• Set units in dimensions to engineering
• Draw a rectangle in XY plane of size 5' x 5'
• Create a region in this rectangle
• Now enter extrude in command
• Select the objects and enter the height 6"
• Select the visual style as shaded
  
  
• 
• Select pyramid tool and specify the centre as centre of object
• Enter the base radius as 2.5'
• Click on top radius and enter the value as 6"
• Now enter the value of height as 2' and click ok
• Set the origin to draw the dimensions
• Using dimlinear dimensions are drawn

RESULT :

3D Model of isometric footing is created

PROBLEM 3 :

AIM : To create 3D view of AASTHO type girder

PROCEDURE :

• Draw a rectangle of sizes
  • 1'6 x 6"
  • 1'6" x 2'
  • 1' x 6" (leave 3" on both side of rectangle)
    
    
• 
• Now draw another rectangle of size 6" x 2' as shown below
  
  
• 
• Create triangles of height and base as
  • H=6" , B=6"
  • H=3" , B=3"
    
    
• 
• Trim off the extra lines as shown below
  
  
• 
  
  
• Using boundary tool create a region of the object
• Now enter extrude in command
• Select the objects and enter the height 10"
  
  
• 
  
  
• Enter "Hide" command and press enter
  
  
• 
  
  
• Enter "Chamferedge" in the command
• Select the edge to be chamfered and enter both the distance 1"
  
  
• 
  
  
• Set the origin to draw the dimensions
• Using dimlinear dimensions are drawn

RESULT :

3D view of AASTHO type girder is created

PROBLEM 4:

AIM : To create 3D model of a drop column with panel

PROCEDURE :

• Set units to engineering
• Set units in dimensions to engineering
• Draw a two rectangles of size 4'6" x 4' 6" in XY plane
• Convert this rectangle into region
• Now enter extrude in command
• Select the objects and enter the height 6"
• Convert visual into shaded
• Select pyramid tool and specify the centre as centre of object
• Enter the base radius as 21"
• Click on top radius and enter the value as 9"
• Enter height value as 1' and press enter
  
  
• 
• Now select cylinder tool and select the center of previous object
• Enter the diameter as 1'6" and height as 10'
• Press enter
  
  
• 
• Set the origin to draw the dimensions
• Using dimlinear dimensions are drawn

RESULT :

3D model of a drop column is created
SHADED VIEW :

2DFRAME VIEW :

Using 3Dorbit object is rotated and viewed in shaded style

PROBLEM 5 :

AIM : To draw 3D model of wall using AutoCad

PROCEDURE :

• Set units to engineering
• Set units in dimensions to engineering
• Draw a rectangle of size 10' x 9"
• Divide the rectangle into 3 parts
  • 3.5' x 9"
  • 3' x 9"
  • 3.5 x 9"
    
    
• 
• Now make boundary for regions shown below using "BO" command
  
  
  
  
• Now enter extrude in command
• Select the objects and enter the height 7'
• Create a rectangle at the top as shown in the fig
  
  
• 
• Convert the rectangle into region and trim off the extra lines below
  
  
• 
• Now draw a triangle of height 5'6" and base length 10'
  
  
• 
• Convert it into region
• Draw a line of 9" perpendicular to triangle
• Select sweep command
• Select the triangle object and select 9" line as path
  
  
• 
• Place this object on the walls
  
  
• 
• Set the origin to draw the dimensions
• Using dimlinear dimensions are drawn

RESULTS:

3D Model wall is created
