Creating various 3D Models in AutoCad.

1.Create a 3D Furniture element as shown in the Figure. Assume dimensions which are missing.

AIM: To create a 3D Furniture element as shown in the Figure.

PROCEDURE

• Open AutoCAD and click the workspace icon
• Enter Units and limits
• Line command is used to draw the 3D object
• Command-line draw 2'6" in the Z direction
• Line of 3' in the Y direction
• Line 2' in a negative Z direction
• Offset 2" as the thickness of the 3D object 
• Assume the width of the object as 2'3"
• Move USC and face in the desired manner
• Use face command place the particular face and show dimensions
•  

Result:

• The 3D furniture element is created in AutoCAD software by using above mentioned procedure as shown below.

2.Create the 3d Model of an Isolated footing as shown in Figure.

AIM: To create the 3d Model of an Isolated footing as shown in Figure. 

PROCEDURE

• Open AutoCAD and click the workspace icon
• Enter Units and limits
• Line command is used to draw the 3D object
• Draw a rectangle (1',1') in the 3D view
• Give offset of 1' to the rectangle on the outside of the rectangle
• Extrude the bigger rectangle to the height of 6"
• Move the inner rectangle at the height of 2'6"
• Join all corners points
• Use the command 3D orbit to move the object in the degree manner and join all the corner points

Result:

3D modal of isolated footing is created in AutoCAD software by following the above mentioned command as shown below.

    • select UN command < select engineering< precision xss=removed>select line command
    • again line command<select midpoint of first-line as the first pointselect first line 
    • select line command<select first point again select second point < join>
    • trim the rest of unwanted lines
    • select offset command< select the second line as object select offset command<select the second line as object select line command
    • select unwanted lines

    

    • select 3D modeling workspace
    • select 3df command<select closed object select 3dr command

    

    • select extrude command<select wall as object
