Cubic Bezier Distance Field

About this Block

What it does: The Cubic Bezier block creates an Implicit Body whose boundary is formed by a smooth, implicit cubic Bézier curve. The shape of the curve is controlled by four points.

Cubic Bezier

Common uses:

Designing aerodynamic profiles for wings, fuselages, and other vehicle bodies.
Modeling smooth transitions in components like ducts, inlets, and nozzles to manage fluid flow.
Creating architectural features like arches and curved facades.

Tips:

For advanced applications, you can use a Ramp or Distance to Curve from Axis block to vary the points.
You would need to combine it with a Boolean Intersect block to create a solid since the block only outputs the implicit surface.
