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

1)

AIM:

• To create a 3D Furniture element as shown in the Figure.
• Assume dimensions which are missing.

PROCEDURE:

• Using Worskspace switching icon 3D Basics workspace is set.
• Using LINE tool the outline is formed.
• Inside the outline a rectangle is created using RECTANGULAR command.
• Using BOUNDARY a surface is created within the outline.
• It is then extruded to form a solid using EXTRUDE command.

• The inner rectangle is also created as a region using REGION command and selecting it as the object.
• It is extruded using ECTRUDE command to the required height.

• The inner solid is then subtracted off using SUBTRACT command to get the required solid.
• It is displayed using HIDE option from Visual styles dropdown.

FINAL RESULT:

The required 3D furniture element has been created as per dimensions.

2)

AIM:

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

PROCEDURE:

• UN command is given and units are set to engineering.
• The precision is set to 0'-0'0".
• A rectangle of given dimensions is drawn using RECTANGULAR command.
• It is then offsetted using OFFSET command and copied and moved in the Z axis using COPY command.

• The edges are then joined using LINE command.

• They are then created into a solid by using #DFACE command and selecting the edges.
• It is displayed using HIDE option from the visual styles dropdown.

FINAL RESULT:

The required Footing has been created.

3)

AIM:

• To create the 3D view of the AASTHO Type Girder.

PROCEDURE:

• The outline is created using Top view from view cube.
• It is created as per the given dimensions with LINE, OFFSET and TRIM tools.
• The Home icon is clicked on the view cube.

• BOUNDARY command is used to create a region within the outline.
• It is then extruded as per dimensions using EXTRUDE command.

FINAL RESULT:

The required 3D view of the AASTHO Type Girder has been created and represented in the Shaded visual style.

4)

AIM:

• To create a 3d Model of a drop column with panel as shown in section and isometric view.

PROCEDURE:

• A rectangle is created of required dimensions using RECTANGULAR command.
• It is then converted into region by REGION command and selecting it as object.
• It is then extruded using EXTRUDE command for required dimensions.

• Another rectangle of same imensions is drawn using RECTANGULAR.
• A circle is drawn from the geometric center of the rectangle using CIRCLE command and moved for required distance in Z axis using MOVE command.
• LOFT is selected from ribbon and the surface is created using the shapes.
• It is then placed on the previously created cuboid using MOVE command.

• A circle is created on top of the previous circle using CIRCLE command.
• It is extruded using EXTRUDE command for required dimensions.

FINAL RESULT:

A 3d Model of a drop column with panel as shown in section and isometric view has been created and is displayed in the Shaded visual style.

5)

AIM:

• To create the 3d model of a wall as shown in Figure.
• Consider wall thickness as 9”.

PROCEDURE:

• Using LINE and TRIM commands the outline of the Wall is created.

• BOUNDARY command is used to create a region within its boundaries.
• It is then Extruded using EXTRUDE command.

FINAL RESULT:

The 3d model of a wall as shown in Figure of wall thickness as 9” is created and displayed in the Shaded visual style.
