Shape Extrusion
Extrudes a Shape along a Path to produce a Volume. This is the core module for procedural mesh generation in the Curvy Generator.

Settings
Path
Controls how the path is sampled during extrusion.
Range
Defines which portion of the path to extrude. For closed paths, From repeats endlessly; for open paths it is clamped.
Resolution
Controls how many segments are created along the path. Higher values produce a smoother result.
Optimize
When enabled, segments are placed based on the path's curvature rather than at a fixed distance. Fewer segments are used on straight sections, more on curves.
Angle Threshold
(Optimize only)
The curvature angle at which a new segment is inserted.
Cross
Controls how the cross-section shape is sampled during extrusion.
Range
Defines which portion of the shape to use as the cross-section. For closed shapes, From repeats endlessly; for open shapes it is clamped.
Resolution
Controls how many vertices are created around the cross-section. Higher values produce a smoother profile.
Optimize
When enabled, vertices are placed based on the shape's curvature rather than at a fixed distance.
Angle Threshold
(Optimize only)
The curvature angle at which a new vertex is inserted.
Include CPs
When enabled, a vertex is guaranteed at every control point of the cross-section shape.
Shift
Defines the starting point of the cross-section relative to the extruded volume.
- None — the shape's own start point is used
- By Orientation — the start is shifted to the collision point of the path's orientation with the shape
- Custom — the start is shifted by a user-defined value
Reverse Normal
Flips the normals of the generated volume (does not affect the Hollow output).
Scale
Controls how the cross-section is scaled along the path. Useful for tapering or swelling effects.
Mode
- Simple — scale by a single value
- Advanced — scale using curves
Reference
- Self — scale is applied over the path's active range
- Source — scale is applied over the path's total length
Uniform Scaling
When enabled, applies the same scale to both X and Y axes of the cross-section.
Scale
The base scale value applied to the cross-section vertices.
Offset
(Advanced mode only)
Scale starts at this offset along the path.
Multiplier
(Advanced mode only)
A curve multiplying the base scale value.
- X axis — Relative Distance (0 = start, 1 = end)
- Y axis — scale multiplier
Hollow
Generates a second, smaller volume inside the main volume simultaneously. The value defines how much the inner volume is shrunk as a percentage.
Reverse Normal
Flips the normals of the hollow volume (does not affect the main Volume output).
