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

WEEK 12 CHALLENGE REPORT

1. Aim is to create the 3D furniture element as shown in the figure using 3D Modeling Workspace. I am going to use UCS Icon, View Cube and Navigation Bar to work easily in different sides of the drawing.

• First step is to open a new page and set the Drawing Units as shown.

• Next I set the max limit of the screen using Command: Limmax 20’,20’

Command: Zoom > All

• Now I Switch the working space

Workspace Switching> From Drafting and Annotation to 3D Modeling

• Is time to start with the drawing of the furniture element.

First thing I do is draw a rectangular using command: Rec with length 3’ and width 1’6”.

• Using command: Extrude I extrude the rectangular with hight of extrusion 2’6”.

• I change the UCS position using command: UCS as shown, and then draw a rectangular same as the face where we placed the UCS , and Offset these rectangular 2”. Then I delete the first rectangular.

• I explode the offseted rectangular, extend the right and left side as shown, and move the bottom side down.

• Using command : Boundary I Region the rectangular created resently.
• Then using command: Extrude I extrude the rectangular with high of extrusion 1,4”

• Using command: Subtract I subtract the iner box from the initial box.

• This is the 3D furniture element in a shade of grey.

• This is the 3D furniture element with dimmensions.

To dimension it first using command: D for dimension style manager , I Create a dimension style with text high 2.5”.

Then I change the UCS position using command: UCS, as required to dimension the element using command: DIMLIN.

• This is the final result of the 3D Furniture Element in a shade of Grey.

2.Aim is to create the 3D model of an Isolated footing as shown in the figure using 3D Modeling Workspace. We are going to use 3D commands: Extrude and Pyramid in order to finish the model. I am going to use UCS Icon, View Cube and Navigation Bar to work easily in different sides of the drawing.

• First we use command:Plan to show in the screen the XY plan.

Then in this plan I draw a rectangular 2’x2’.

• Then using command Extrude, I extrude it with heigh 6”.

• Using command: Pyramid with top radius 6” and high 2’.

• This is the final 3D model of the Isolated footing with dimmensions.

To dimension it first using command: D for dimension style manager , I Create a dimension style with text high 3”.

Then I change the UCS position using command: UCS, as required to dimension the element using command: DIMLIN.

3.Aim is to create the 3D view of the AASTHO Type Girder using 3D Model Workspace. I am going to use commands: Line, Mirror, Region, Extrude.. I am going to use UCS Icon, View Cube and Navigation Bar to work easily in different sides of the drawing.

• First using command Line, in the XY plan I draw the figure as shown.

Next I Mirror it in the other side of the drawing.

• This is the profile of the girder in the XY plan.

To dimension it first using command: D for dimension style manager , I Create a dimension style with text high 4”.

Then I change the UCS position using command: UCS, as required to dimension the element using command: DIMLIN.

• Using command: Boundary I create a region out of the profile.

• Using command: Extrude with heigh 10’ I extrude the profile in the Z direction.

• This is the 3D view of the AASTHO Type Grider in a shade of gray in different directions.

4.Aim is to create a 3D model of a drop column with panel as shown in section and isometric view using 3D Model Workspace.

I am going to use commands: Rec, Region, Extrude, Circle, 3D Move, Loft, Presspull.

I am going to use UCS Icon, View Cube and Navigation Bar to work easily in different sides of the drawing.

• First I draw a Rec with dim:4’6”x4’6”

I use command: Extrude to extrude the rec with heigh 6”.

• I place the UCS in the top face of the box, draw a rec in this face and offset it with distance 6”. Then I delete the first rectang.
• In the center of the offseted rectang, I draw a circle with diameter 1’6”.
• Then using command: 3D Move I move the circle in the Z direction 1’.

• I use command : Loft to create the element betwen rectangle and circle.

• I use command: Presspull to pull the face of the circle with a high of 10’.

• To dimension it first using command: D for dimension style manager , I Create a dimension style with text high 4”.

Then I change the UCS position using command: UCS, as required to dimension the element using command: DIMLIN.

This is the final result of the drop column as a 3D model in a shade of gray.

5. Aim is to create a 3D model of a wall with a thickness of 9” as shown using 3D Model Workspace. I am going to use commands: Rec, explode, Region, Extrude, 3D Move, Union, Chamfer edge.

I am going to use UCS Icon, View Cube and Navigation Bar to work easily in different sides of the drawing.

• First I use command: rec to create a rec 10’x9”

Then I Explode the rec, and offset the left and right side with 3’6”.

I use command: Region to create the regions as shown.

• I use command Extrude, heigh 12’6” to extrude the regions.

• In the space between two 3d columns, I create a rectangle, and using 3D Move I move it to the Z direction with 7’,

Then I Extrude it in the same heigh as the other two columns.

• I use command: Union to union the different parts of the wall.

• To create the roof I use command: Chamfer Edges with distance 2’ and 5’ as shown on both top right and left edges of the wall.

• To dimension it first using command: D for dimension style manager , I Create a dimension style with text high 4”.

Then I change the UCS position using command: UCS, as required to dimension the element using command: DIMLIN.

• After deleting the extra lines, This is the final result of the 3D model of the wall shaded with edge.
