ArrayCrv

ArrayCrv makes it easy to distribute and align objects along any curve, with interactive control over spacing, scale, orientation, and repetition. Industrial designers can quickly create patterns for products like speaker grilles, footwear, tire treads, or textured surface finishes, while automatically adapting objects to the shape of the geometry.

Interactive UI

The new in-viewport controls provide an intuitive way to quickly adjust scale, span, positioning, and more. These controls sync with the settings in the ArrayCrv dialog and command line, providing a seamless transition between control methods.

Added Flexibility

ArrayCrv gives you interactive control over how objects are distributed along curves, with real-time adjustments for count, spacing, offsets, rotation, and scale. Jewelry designers can quickly create gemstone layouts, prong settings, chain links, and decorative patterns that automatically follow the design’s curvature.

For Architectural Details

ArrayCrv provides a streamlined approach to creating architectural details and repeating elements in interior and exterior design.
