Creating 3D Isometric view of various structural elements in AutoCAD
3D ISOMETRIC VIEW OF THE BUILDING
Aim: To create a 3D Isometric View of the building with given plan and elevation in AutoCAD 3D modelling
Introduction: The 3D Isometric View of the building is created in AutoCAD using 3D modelling tool.
The main objective of this project is to understand about AutoCAD 3D, applying materials and rendering. AutoCAD is primarily used for generating 2D sketches. While it is possible to create 3D objects, AutoCAD is built around a flat, sketch-based interface. There is a wide range of pre-defined 3D objects in AutoCAD. These objects are cylinders, spheres and wedges and many more. But then users use 2D objects and modify them using the 3D commands accordingly. So, AutoCAD 3D commands like Extrude, Sweep, Revolve, Union are used by the users. Also, the user must know the importance of the Viewport feature if they are working on 3D Models. The viewport command allows the user to split the drawing area into different windows to project multiple views of the model. These include the top, front, left/right views of the object. This feature works great for the user and helps them to observe the model from different aspects.
The procedure of drawing is explained and the final results are given.

Procedure:
Open the AutoCAD, switch to 3D modelling by clicking on workspace switching and click on the home button near the view cube.
Type unit or UN in the command line and press enter
Set type of unit as engineering and precision as 0’ 0”
In insertion scale set unit as Inch.
Set upper limit and lower limit of the drawing
Set the limits and zoom - all.
Here first have to draw the wall using the line command, as shown in the figure.
Next, we have to draw the two windows of sizes of 3’ and 3'-2"
Change the view to 3D by clicking on home button of view cube
Set UCS as world
Use Press pull tool to extrude boundaries to total height of 10’
Draw rectangles at both windows and extrude them to height of 3’
Draw rectangles at top of both window openings and extrude them downside to 3’ to provide window opening
Select all the wall and use union command to them as single solid object
Creating Elevation Windows
Draw a rectangle of dimension 3’,4’
Offset the rectangle to inside to distance of 3”
Then offset the rectangle again inside to distance of 4”
Start the boundary command and click on pick points
Click inside the window frame area and press enter
Type SUBTRACT command
Select the bigger region and then select the smaller regions to subtract them.
Follow the same procedure for all the three boxes.
Now using the MOVE command place the window at the correct position as shown.
The floor and roof are created using extrudes command.
For the 3D model color applied to look better
RESULT
The 3D Isometric View of the building is created using AutoCAD 3D modelling

Here first have to draw the wall using the line command, as shown in the figure.
Create the window opening of dimensions 3’ wide as shown in figure
Add dimensions using dimension tool
Change the view to 3d by clicking on home button of view cube
Set UCS as world
Set the view style control as SHADED
Extrude the boundaries created to total height of 40’10”
Type UCS in command line and select view to create user UCS
Then use rectangle tool to create window of size 3’,4’ and use copy to replicate
Use move tool to place the window at exact positions
Extrude the rectangle and use subtract the extruded solid to create window openings
Switch UCS again to view and use dimension tools to provide dimensions
Creating Elevation Windows
Type UCS and click on face and select the face having 3' wide window
Draw a rectangle of dimension 3',4'
Offset the rectangle to inside to distance of 2"
Offset the inside rectangle to inside at a distance of 3"
Add dimensions using dimension tool
Start the boundary command and click on pick points
Click inside the window frame area and press enter
Type SUBTRACT command
Select the bigger region and then select the smaller regions to subtract them.
Follow the same procedure for all the three boxes.
The upper part of building was then drawn using line command 4” wall with height 6’5” from top
Create a boundary for the wall
Extrude the boundary to 9” as shown in elevation
Now put the building facade in the 3d isometric view using the 3dorbit command as shown in the below figure.
RESULT
The given 3d isometric view of the building facade is drawn successfully in the AutoCAD 3D modelling
3D VIEW OF A STAIR WITH RAILING
