How do we use the revolve command to create an object in AutoCAD?
Creates a 3D solid or surface by sweeping an object around an axis.
Summary
Open profiles create surfaces and closed profiles can create either a solid or a surface. The MOde option controls is a solid of surface is created. When creating a surface, SURFACEMODELINGMODE system variable controls if a procedural or NURBS surface is created.
Revolve path and profile curves can be:
- Open or closed
- Planar or non-planar
- Solid and surface edges
- A single object (to extrude multiple lines, convert them to a single object with the JOIN command)
- A single region (to extrude multiple regions, first convert them to a single object with the UNION command)
Objects That Can Be Revolved
| Surfaces | Elliptical arcs | 2D solids |
| Solids | 2D and 3D splines | Traces |
| Arcs | 2D and 3D polylines | Ellipses |
| Circles | Regions |
Revolving An Object
1. Type Rev
2. Press Enter
3. Select the object to revovle
4. Press Enter
5. Select the Axis start Point and end point
6. Choose an angle of Revolution
List of Prompts
The following prompts are displayed.
- Objects to Revolve
-
Specifies the objects to be revolved about an axis.
- Mode
-
Controls whether the revolve action creates a solid or a surface. Surfaces are extended as either NURBS surfaces or procedural surfaces, depending on the SURFACEMODELINGMODE system variable.
- Axis Start Point
-
Specifies the first point of the axis of revolution. The positive axis direction is from the first to the second point.
- Axis Endpoint
-
Sets the endpoint for the axis of revolution.
- Start Angle
-
Specifies an offset for the revolution from the plane of the object being revolved.
Drag your cursor to specify and preview the start angle of the object.
- Angle of Revolution
-
Specifies how far the selected object revolves about the axis.
A positive angle revolves the objects in a counterclockwise direction. A negative angle revolves the objects in a clockwise direction. You can also drag the cursor to specify and preview the angle of revolution.
You can use lines, linear polyline segments, and linear edges of solids or surfaces as an axis.
