API Reference > geometry-core > Curve > LineString3d > createRectangleXY createRectangleXY MethodStatic Create the linestring for a rectangle parallel to the xy plane. The z coordinate from point0 is used for all points. ax and ay are signed. The point sequence is: Start at point0 move by (signed !) ax in the x direction. move by (signed !) ay in the y direction. move by (signed !) negative ax in the x direction. move by (signed !) negative ay in the y direction. (this returns to point0) createRectangleXY(point0: Point3d, ax: number, ay: number, closed: boolean = true): LineString3d Parameter Type Description point0 Point3d ax number ay number closed boolean Returns - LineString3d Defined in curve/LineString3d.ts Line 367 Last Updated: 11 June, 2024
