How to Use the Revolve Command in AutoCAD?

Understanding the Revolve Command in AutoCAD

The Revolve command in AutoCAD is fundamental for creating 3D objects from 2D profiles. This feature transforms a 2D shape into a three-dimensional solid by rotating the shape around a specified axis. It is commonly used in design tasks where creating symmetrical shapes such as bowls, shafts, and cylindrical forms is required.

Steps to Use the Revolve Command

To utilize the Revolve command in AutoCAD effectively, follow these steps:

1. Accessing the Command

Navigate to the Solid tab located on the ribbon. Within the Create panel, you will find the option labeled “Revolve.” Click on it to initiate the command.

2. Selecting the Profile

After activating the command, select a closed 2D shape that you wish to revolve. Ensure that the shape is entirely enclosed; otherwise, the command will not function correctly.

3. Defining the Axis of Revolution

Specify the axis around which the shape will revolve. You will need to set a start point and an endpoint for this axis. Click on the two points on the screen, which will orient the shape based on the defined axis. This step is critical as it determines the rotational direction of the resulting 3D object.

4. Finalizing the Operation

Press the Enter key to complete the command. It’s important to note that to create a full 3D solid, the angle of revolution must be set to 360 degrees. If you wish to create a partial revolution, specify the angle accordingly.

Troubleshooting Revolve Issues in AutoCAD

If you encounter difficulties while using the Revolve command, a common solution is converting your 2D object into a polyline. This can be accomplished using the “bpoly” command to create a boundary polyline. After this conversion, you should be able to successfully execute the Revolve command.

Utilizing the Revolve Command for 3D Modeling

To further enhance your skills in 3D modeling with the Revolve command, you may find it beneficial to refer to tutorial videos that guide you through practical examples. Learning from visual demonstrations can solidify your understanding of the command and its applications in various design projects.

Common Questions About the Revolve Command

1. Can I revolve an open shape in AutoCAD?

No, the Revolve command requires a closed shape. If your shape is open, you will need to close it before using the command.

2. What types of objects can I create with the Revolve command?

The Revolve command is versatile and can be used to create various objects, including cylindrical forms, bowls, and other symmetrical shapes. Depending on the 2D profile used, you can generate a wide range of 3D geometries.

3. Is there a shortcut for the Revolve command in AutoCAD?

Yes, you can type “REVOLVE” in the command line to quickly execute the command without navigating through the menus. This often speeds up the modelling process.
