Summary

You can revolve closed objects to create 3D solids and open objects to create surfaces. Objects can be revolved 360 degrees or another specified angle.

With the REVOLVE command, you can create a new solid or surface by revolving an open or closed planar curve about an axis. You can revolve more than one object.

The DELOBJ system variable controls whether revolved objects are automatically deleted when the solid or surface is created or whether you are prompted to delete the objects.

You can select the objects to revolve before you start the command.

You can revolve the following objects:

Objects that Can Be Revolved

Object types
2D solids
3D faces - planar
Arcs
Circles
Ellipses
Elliptical arcs
Lines
Polylines - 2D
Regions
Solids - planar faces
Splines - 2D
Surfaces - planar faces
Traces
NoteYou can select faces on solids by pressing and holding CTRL, and then selecting these subobjects.

You cannot revolve objects contained within a block. Polylines that have crossing or self-intersecting segments cannot be revolved. REVOLVE ignores the width of a polyline and revolves from the center of the path of the polyline.

The right-hand rule determines the positive direction of rotation. See Control the User Coordinate System in 3Din the User's Guide.

List of Prompts

Object to Revolve

Specifies the objects to be revolved about an axis.

Axis Start Point

Specifies the first and second points of the axis of revolution. The positive axis direction is from the first to the second point.

Start angle

Specifies an offset for the revolution from the plane of the object being revolved.

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.

The objects are revolved to the specified angle.

Object

Specifies an existing object to be used as an axis. The positive axis direction is from the closest to the farthest endpoint of this object.

You can use lines, linear polyline segments, and linear edges of solids or surfaces as an axis:

NoteYou can select an edge on a solid by pressing and holding CTRL, and then selecting an edge.
X (Axis)

Sets the positive X axis of the current UCS as the positive axis direction.

Y (Axis)

Sets the positive Y axis of the current UCS as the positive axis direction.

Z (Axis)

Sets the positive Z axis of the current UCS as the positive axis direction.
