Revolve

Use Revolve to rotate a 2D sketch profile around an axis, generating rotationally symmetric solids. Revolve is ideal for creating shafts, bottles, flanges, turned components, and any geometry with circular symmetry.

Options

Sketches

Select the sketch profile you want to revolve. Make sure the sketch doesn't cross the axis of revolution - that would create invalid geometry with the surface intersecting itself.

Axis Type

Choose whether to revolve around a standard sketch axis (X, Y, or Z) or around an existing edge in your model.

Sketch Axis

If you chose "Sketch Axis" above, pick which axis: X, Y, or Z in your sketch's coordinate system. The profile will spin around this axis.

Edge

If you chose "Edge" above, select a straight edge from your existing geometry to use as the revolution axis.

Angle

How many degrees to rotate. Common choices:

• 360 - Full revolution (shaft, bottle, bowl)
• 180 - Half revolution
• Any custom angle for partial features

Symmetric

Enable this to revolve equally in both directions from the sketch. Your specified angle gets split in half - rotating both ways from the starting position.

Bidirectional Angle

When creating a non-symmetric bidirectional revolve, this sets the rotation amount in the opposite direction.

Start Tag and End Tag

Tag the start face (at the sketch location) or end face (at the final rotation angle) to reference them in later features.

Body Type

Choose solid for a watertight 3D body, or surface for a thin shell with no thickness. Most parts use solid.
