The Revolve command creates a surface or SubD by revolving a profile curve that defines the surface shape around an axis.

Steps

  1. Select curves.

  2. Pick the start of the revolve axis.

  3. Pick the end of the revolve axis, or press Enter to use CPlane-Z direction.

    The start and end of the revolve axis can be attached to existing objects using object snaps when History is recorded.

  4. Specify options.

Command-line options

Output (Surface/SubD)

Specifies to create a NURBS surface or SubD.

DeleteInput

Deletes (Yes) or keeps (No) the input object.

FullCircle

Revolves the input curve 360 degrees as a shortcut for specifying 360 degrees as the revolve angle.

AskForStartAngle
Yes

Allows setting the angle (a degree away from the current input curve location) the revolve will start.

No

Starts the revolve from 0 (the input curve location).

Deformable

This option is only available when Output=Surface.

Yes

The surface is rebuilt in the revolving direction to a degree-3 non-rational surface. Specify how many points in that direction. Deformable revolves can be deformed smoothly with point editing.

No

The resulting revolved surface is an exact revolve: a rational surface with fully-multiple knots at the quadrants. This kind of surface is not easy to deform smoothly by point editing.

PointCount

Specifies the number of control points in the revolving direction when Output=Surface and Deformable=Yes.

SegmentCount

Specifies the number of faces in the revolving direction when Output=SubD.

SplitAtTangents

Revolves tangent points on the input curve into joined edges (Yes) or creases (No) when Output=Surface.

SplitAtTangents=Yes (left) and No (right).

Wikipedia: Tangent

SubCrv

Type subcrv to select part of a curve as input.
