How to Create Revolve Features in SOLIDWORKS

Revolve features in SOLIDWORKS create 3D geometry by rotating a sketch profile around an axis. They are useful for shafts, knobs, pulleys, bushings, cones, grooves, and many round or turned parts.

Start with a clean sketch

Create a sketch that represents the cross-section of the part. The sketch should include only the profile that needs to rotate. Fully define the sketch with dimensions and relations so the revolve behaves predictably when the part is edited.

For turned parts, it is often best to sketch half of the section and revolve it around a centerline. This keeps the model simple and close to how the part may be machined.

Include important diameters and axial lengths directly in the sketch where practical. That makes the revolved profile easier to compare with a lathe drawing or inspection requirement.

Choose the revolve axis

The revolve axis can be a centerline in the sketch, a model edge, an axis, or suitable reference geometry. The selected axis controls the final shape, so check the preview before accepting the feature.

If the preview looks like a self-intersecting or oversized shape, the profile may cross the axis or the wrong axis may be selected.

The axis should be stable and easy to find later. A named centerline or default reference axis is usually better than an edge that might disappear after future edits.

Create a revolved boss or base

1. Create the sketch profile.
2. Add or select the revolve axis.
3. Open Revolved Boss/Base.
4. Select the profile and axis.
5. Set the revolve angle.
6. Confirm the preview and rebuild.

Use revolved cuts

A revolved cut removes material by rotating a cut profile around an axis. It is useful for grooves, chamfers, internal reliefs, counterbores, and turned recesses. The setup is similar to a revolved boss, but the feature removes material instead of adding it.

When using a revolved cut, confirm that the cut profile intersects the body where material should be removed. A valid-looking sketch may do nothing if it is positioned away from the solid body.

Revolved cuts are also useful for machining reliefs and internal grooves. Keep those details dimensioned clearly so the drawing can communicate the same geometry to manufacturing.

Control angles and thin features

Most revolve features use a full 360-degree rotation, but partial revolves are useful for handles, stops, and features that should not go all the way around. Thin feature options can create wall thickness from an open sketch where appropriate.

Use partial angles carefully and define them with dimensions or design intent. If the angle affects clearance or assembly function, check it in context.

Thin revolves can be useful, but they should be used intentionally. If wall thickness is important for strength, weight, or manufacturing, confirm the final section with a section view and mass properties.

Troubleshooting

If a revolve fails, check for open profiles, overlapping sketch entities, profiles crossing the axis, or an invalid axis selection. Use the sketch repair tools if the profile will not select cleanly.

Revolve features are strongest when the sketch is simple. Avoid putting every detail into one complicated revolve if separate features would be easier to edit and understand.

Before releasing a revolved part, check dimensions, mass properties, and any drawing sections that describe the turned profile. Small sketch errors can create large manufacturing differences in round parts.

For parts that will be turned on a lathe, review whether the profile can actually be machined with the intended tools. Sharp internal corners, deep narrow grooves, and small reliefs may need design adjustments.
