Knot is an addon that generates mathematical knot geometries directly within the 3D viewport. It allows users to create torus knots, twist knots, and complex weaves using parametric controls. The tool includes adjustable parameters for radius, segment count, twists, and pattern variations. It features a custom tab in the viewport, a live update button for real-time adjustments, and content-aware editing capabilities, making it suitable for jewelry design, abstract visualization, and mathematical modeling.
