Creating various 3D Models like Furniture, Footing, Girder, Column drop with panel and Gable Wall in AutoCad

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

1) Figure : 3D Furniture

Procedure:

Steps:

• Open a new drawing in imperial settings
• Now change the workspace to 3D modelling
• Use line command
  • Specify first point
  • Specify next point - @0,0,2'6"
  • Specify next point - @0,3',0
  • Specify next point - @0,0,-2'6"
  • Specify next point - @0,-2",0
  • Specify next point - @0,0,2'4"
  • Specify next point - @0,-2'8",0
  • Specify next point - @0,,0,-2'4"
  • Specify next point - @0,-2",0
• Now use join command
• Use region command
• Now use extrude command to extrude it 2' in x-axis
• Change the view and join the bottom legs
• Make the view to hidden
• Use dimlinear command to give dimensioning
• Use UCS option to chanfe face while dimensioning

Result:

2) Figure: Isolated Footing

Procedure:

Steps:

• Use rec command to make a square of 1'
• Use region cammand and select the square
• Now use extrude command and select the object
  • Then select the taper angle option and give the value = -45
  • Specify height of extrusion = 2'
• Now change the view so thst we can see bottom face
• now use presspull comand and pull the face at a distance of 6"
• now set the view to default
• Use dimlinear commad to give dimension
• Use UCS option to chanfe face while dimensioning

Result:

3) Figure: AASTHO type Girder

Procedure:

Steps:

• Use line command To make the I section
• Now use join commad
• Use region command to give the surface
• Use the Extrude command and extrude the I section at a distance of 10'
• Use dimlinear command to provide dimensions
• Use UCS ooption To change faces of xy plane while dimensioning

Result:

4) Figure: drop column with panel

Procedure:

Steps:

• Use rec commad to create rectangle of 4'6"x4'6" in zx Plane
• Use extrude command to extrude 6" in y-axis
• Use cone commad to create a cone at the centre of rec
  • Specify the diameter 3'6"
  • Select the top radius option
  • Specify the radius - 9"
  • Specify the height - 1'
• Use presspull option and pull 10' in y-axis
• Use dim linear command to give dimension

Result:

5) Figure: 3d model of a wall

Procedure:

Steps:

• Use line command to create the wall structure
• Use region commad
• Use ectrude commad and extude the wall at 9" in y-axis
• make the vie to 2d wireframe
• now use line commad and join the mid points of wall at bottom
• extrude it at 7' in z axis
• Use subtract command to subtract it with wall
• Use dimlinear to provide dimensions

Result:
