API Reference > geometry-core > CartesianGeometry > ConvexClipPlaneSet > createSweptPolyline createSweptPolyline MethodStatic Create a convex clip set for a polygon swept with possible tilt angle. planes are constructed by ClipPlane.createEdgeAndUpVector, using successive points from the array. If the first and last points match, the polygon area is checked. If the area is negative, points are used in reverse order. If first and last points do not match, points are used in order given createSweptPolyline(points: Point3d[], upVector: Vector3d, tiltAngle?: Angle): undefined | ConvexClipPlaneSet Parameter Type Description points Point3d[] polygon points. (Closure point optional) upVector Vector3d primary sweep direction, as applied by ClipPlane.createEdgeAndUpVector tiltAngle Angle angle to tilt sweep planes away from the sweep direction. Returns - undefined | ConvexClipPlaneSet Defined in clipping/ConvexClipPlaneSet.ts Line 524 Last Updated: 11 June, 2024
