How to Use the Revolve Command in AutoCAD

Understanding the Revolve Command in AutoCAD

The Revolve command in AutoCAD allows you to create complex 3D shapes by rotating a 2D object around a specified axis. This additive methodology is particularly useful for generating objects like cylinders, spheres, and more intricate designs that require a rotational symmetry.

Steps to Execute the Revolve Command

Step 1: Initiate the Command

Begin by accessing the appropriate workspace. Navigate to the Solid tab located in the Create panel. Look for the option labeled “Revolve” and click on it to initiate the command.

Step 2: Select the Object

Once the command is activated, you will be prompted to select a closed polyline or any closed shape on your workspace. This selection will be the profile that will be revolved to create the 3D object.

Step 3: Define the Axis of Revolution

Specify the axis around which you want to revolve the selected object. You can do this by clicking on two different points in your workspace, which will indicate the start and endpoint of your chosen axis. The orientation of this axis will dictate the final shape of your 3D object.

Step 4: Specify the Revolution Angle

Press the Enter key to confirm your selections. If you intend to create a full 3D solid, ensure that the angle of revolution is set to 360 degrees. This completes the circular sweep around the axis.

Utilizing Commands in AutoCAD

Effective use of commands is crucial for efficient navigation and operation within AutoCAD. To input a command:

  1. Type the complete command name into the Command prompt and press Enter or the Spacebar.
  2. If you prefer, use an alias of the command for quicker access. These aliases are usually predefined but can be customized to fit your preferences.

3D Modeling Basics in AutoCAD

Understanding the 3D modeling capabilities of AutoCAD is essential for more advanced designs. AutoCAD provides an intuitive interface for drafting in three dimensions. Familiarize yourself with key operations such as moving, aligning, and manipulating objects to make the most of your design process.

Frequently Asked Questions

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

The Revolve command can transform any closed profile, such as circles, rectangles, or custom shapes, into 3D forms like pipes, vases, or other symmetrical objects. The versatility of shapes allows for a myriad of designs.

Can I edit the 3D object created by the Revolve command afterward?

Yes, once the 3D object has been created, you can utilize various tools within AutoCAD to modify it, such as scaling, moving, or applying additional boolean operations to further manipulate the model as needed.

Is it possible to use the Revolve command in AutoCAD 2025 for non-closed shapes?

No, the Revolve command specifically requires closed shapes to function correctly. If your shape is not closed, consider using other commands to first create a closed profile before applying the Revolve operation.
