How to Use the SOLIDWORKS Deform Feature

Contents

The SOLIDWORKS Deform feature changes the shape of existing geometry using methods such as point deform, curve-to-curve deform, and surface push. It is useful for organic shapes, ergonomic surfaces, quick concept changes, and forms that are difficult to build with simple extrudes or cuts.

Use Deform carefully. It can create useful shapes quickly, but the resulting geometry may be harder to dimension, manufacture, or edit than a model built from simpler features.

SOLIDWORKS Deform feature example — Deform changes existing geometry rather than creating a basic sketch feature.

Open the Deform feature

Open the part you want to modify.
Go to Insert > Features > Deform.
Choose the deform type that fits the shape change.
Select the required faces, bodies, curves, points, or tool geometry.
Preview the deformation.
Accept the feature and rebuild the model.

Deform feature controls in SOLIDWORKS — The Deform PropertyManager changes depending on the deform type.

Choose the right Deform type

Point deform: pulls or pushes geometry from a selected point.
Curve to curve: changes geometry by matching an initial curve to a target curve.
Surface push: pushes target faces using another surface or body.

Curve-to-curve is often best when you need a controlled transition. Surface push is useful when another body or surface defines the desired shape. Point deform is quick, but it can be less predictable for precise geometry.

Preview before accepting

Always rotate the model and inspect the preview. Look for folded faces, self-intersections, small sliver surfaces, and areas that no longer match manufacturing intent. If the preview looks messy, reduce the deformation or use a more controlled feature strategy.

Previewing a Deform feature in SOLIDWORKS — Inspect the preview from several angles before accepting the feature.

When Deform is useful

Deform is helpful for quick concept modeling, molded shapes, ergonomic grips, surface transitions, and models where the visual or fit result matters more than a simple feature tree. If the part is manufacturing-critical, use Deform only after confirming the final geometry can be inspected and produced.

Finished SOLIDWORKS Deform feature — Use Deform when the shape change is easier to control through deformation than standard features.

Troubleshooting

The feature fails: reduce the deformation amount or simplify the selected region.
The wrong area changes: review selected faces, bodies, or deform direction.
The shape is too hard to control: try curve-to-curve instead of point deform.
The part is hard to manufacture: rebuild the shape with sketches, lofts, sweeps, or surfaces.
