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

1.ANSWER

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

PROCEDURE:

• Open the new drawing sheet and change the units from metric to engineering and precision 0’-0”.

Used commands:

• Rectangle
• Region
• Extrude
• UCS
• Move
• Subtract
• 3D orbit

Create a rectangle 2’-0 X 3’-0” by using REC Enter in the 2D wireframe mode in top view.

Then change the view by clicking the corner of WCS ICON or change the top view to isometric.

• Using a region by typing REG in the command prompt for making rectangle into solid.

• Using a extrude command from the ribbon.
• Extrude the solid to the depth of 2’-6” ENTER.

• Create another rectangle at a required face by using UCS command by typing UCS in the command prompt.
• Then Select a required face.

• Here iam using different layer for the internal rectangle for more clarity.
• Then move the rectangle to the solid place at required position.
• Apply region by REG ENTER.

• Then Extrude the inner rectangle.
• For subtracting use Subtract command in the command prompt.
• Use 3DORBIT for clear view.

RESULT:

2.ANSWER

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

PROCEDURE:

• Create two Rectangles by using REC ENTER.

• Using Move command to move the centre rectangle at z-axis with 2’-0” ENTER.

• Using Loft and Extrude commands to create the geometry.

RESULT:

3.ANSWER

AIM: Create the 3D view of the AASTHO Type Girder.

PROCEDURE:

• Using the Line command for creating a face of AASTHO girder in 2D wireframe.
• Using Fillet command for the fillet the edges 1” radius.

• Apply the region to the geometry.
• Using extrude by typing EXT in the command prompt.
• Extrude the girder span of 10’-0” ENTER.

• Change the 2D wireframe to Shadded view.

RESULT:

4.ANSWER

AIM: Create a 3d Model of a drop column with panel as shown in section and isometric view.

PROCEDURE:

• Using circle command for creating the circular column.

• Apply the region command to make a circle into solid.

• Using Extrude command for height of the column towards Z-axis with 10’-0” ENTER.

• Use UCS command to work on the required face.

• Then create a rectangle and extrude with a Tamper angle 46 degrees with height of 2’-0” ENTER.
• Then using the Press pull command to lift the top face of the panel.

RESULT:

5.ANSWER

AIM: Create the 3d model of a wall as shown in Figure. Consider wall thickness as 9”.

PROCEDURE:

• Using Line command to create 3d model wall in the isometric view.
• Create a wall with required dimensions.

• Then Apply the region to the geometry for make it into solid.
• Then extrude by EXT ENTER → extrude with 9” thickness of the wall.

RESULT:
