Creating 3D Isometric view of various structural elements in AutoCAD

Aim:

To create 3D isometric view for various structural elements such as a Plan, Staircase, Wall Footing and Building Facade using AutoCAD 3D Tools.

Introduction:

• The Drafting of 3D objects can be done using the 3D Modelling option in AutoCAD software.
• It helps to create and visualise the 3D objects which are created.
• We can also render the image after assigning certain material properties to the objects such as Wall Paint, Furniture etc.,
• The various commands used in Creating the 3D models are:
  • Extrude
  • Region
  • Boundary
  • Press and Pull
  • Sweep
  • Circle
  • Rectangle
  • UCS
  • Copy
  • Move
  • Dimension Linear
  • Pyramid
  • Cone
  • Revolve
  • Solid Edit
  • Fillet Edge
  • Chamfer
  • 3D Mirror
  • 3D Align
  • Rendering
  • Material Library
  • Rendening Properties
  • Subtract
  • Union

Procedure:

1. Isometric View of Building Plan:

• Firstly develop the plan of the building or room as shown.
• Then using the region or boundary command create a surface.
• Using the extrude command extend the surface to the required height.
• Create the cross section of window as per the dimensions required.
• Follow the same procedure same as the plan to the window.
• Using the subtract command subtract window portion from the wall layer.

2. Building Facade:

• Create the plan on the XY Plane using the specified dimensions.
• Create regions for different objects and extrude as per the requirement.
• Now using the subtract and union apply them along the elevation where ever needed.
• We can also give different colours to the different layers present in the Drawing.

3. Staircase:

• Firstly create the section of the Staircase on the YZ Plane using the UCS command.
• Now create a region and use the extrude command to stretch the object as per required distance.
• Now to create the Railing and Balustrade use the help of Sweep and Polyline option.

4. Wall Footing:

• Create the section of the Wall Footing on the YZ Plane with help of UCS option.
• Create a region for the Section with the help of region or boundary command.
• With the help of Extrude command extend the section for the required length.
• Now create anoher solid with the dimension of door and sunshade.
• Using the Subtract command subtract the area of door from the solid wall footing.
• Now from the Material properties option assign properties to the wall such as Wood with some finishing.
• Wall Painting can also be provided to the wall and different colours to the Footings as well.
• After assigning material properties now we can render the image of the object.
• Using the render command and render properties manager we can select the quality of render and types of render we need to require for the solid object.
• Save the rendered image of required file type such as PNG or JPG etc.,

Result:

We have created 3D isometric view for various structural elements such as a Plan, Staircase, Wall Footing and Building Facade along with rendering using AutoCAD 3D Tools.

The respective drawing and Rendered images are attached
