# generateBox(size:majorCornerRadius:minorCornerRadius:) Creates a box mesh from a vector of three scalar values that represent width, height, and depth, respectively, and radii for the corners. ``` @MainActor @preconcurrency static func generateBox(size: SIMD3, majorCornerRadius: Float = 0.2, minorCornerRadius: Float = 0.05) -> MeshResource ``` ## Parameters `size` The length of the box’s width, height, and depth, in meters, along the x-, y-, and z-axis, respectively. `majorCornerRadius` The radius of each corner’s circular arc, in meters, orthogonal to the z-axis. `minorCornerRadius` The radius of each corner’s circular arc, in meters, orthogonal to the x-axis. ## Discussion The method centers the box at the entity’s origin and aligns the box’s faces with the coordinate system’s axes. --- Copyright © 2026 Apple Inc.
