Point3d point3d = new Point3d(2, 3, 4); Plane plane = new Plane(new Point3d(0, 0, 0), new Vector3d(0, 0, 1)); Point2d point2d = plane.Convert2d(point3d);
Point3d point3d = new Point3d(5, 5, 5); Vector3d planeNormal = new Vector3d(0, 1, 1); Plane plane = new Plane(point3d, planeNormal); Point2d point2d = plane.Convert2d(point3d);Explanation: This code creates a Point3d with coordinates (5, 5, 5), and a custom plane with its origin at the same point and a normal vector pointing in the direction of (0, 1, 1). The Convert2d method is used to convert the 3D point to a 2D point on the custom plane. The resulting Point2d object will have x-coordinate (5, 5) and a y-coordinate of 0. Package library: RhinoCommon
