Heart Shape
This effect replaces the circular cross-section with a classic heart silhouette. Width and length set horizontal and vertical extent independently, so you can stretch or squash the symbol to fit your design. It defines path geometry (not bump-style displacement), does not support Growth Curve, and pairs well with decorative profiles for gifts and themed prints.

Parameters
Width (mm)- Horizontal extent of the heart (1–500 mm).
Length (mm)- Vertical extent of the heart (1–500 mm).
Spiral (°)- Rotation of the heart that increases with height (−1800° to 1800°).
Phase- Angular offset of the heart around the layer (0–6.28 rad).
How It Works
The heart outline is built from an implicit heart curve, sampled into a closed loop that becomes the cross-section at each height. Your profile scales how large that loop is along the model; Spiral and Phase only reorient the silhouette around the central axis.
This is the same class of control as other shape effects: the wall follows the heart boundary rather than starting from a circle plus displacement. Growth Curve is unavailable because the effect is pure cross-section definition.
