Organic shapes are the cornerstone of modern, soft-UI design. The Convex Waist tool (also known as Waist Path) provides a unique way to generate these shapes by connecting circular nodes with "waists"—inwardly curved tangent paths.
What is a Waist Path?
While standard fillets curve outward to bridge shapes, a "waist" curves inward. This mimics the look of a literal waistline or the narrowing point between two soft bodies, perfect for creating "molten" or organic effects.
Sculpting with Convexity
The real magic happens when you adjust the Fillet Radius (or waist thickness). By manipulating these values alongside node positioning, you can transform a set of simple circles into a unified, flowing blob.

Best Use Cases: - **Blob Backgrounds**: Generate those popular "soft blob" backgrounds for landing pages. - **Custom Icons**: Design organic-looking iconography for startups. - **Abstract Patterns**: Layer multiple wait-generated shapes for depth and flow.
The Convex Waist tool is an essential part of the SVG Flux suite for any designer looking to move beyond rigid grids and into the world of organic flow.
