Bar on the x, y, z axis is defined as shown above, the direction of the x-direction along the keel, the surface normal direction for the y direction, the direction of the tangent surface z direction

X, y, z defined on the bars as shown above, along the keel to the x direction, the surface normal directions of the y direction, surface tangent orientation is the z-direction

On the member X, Y, the Z axis definition like on chart shows, along the keel direction is X direction, the curved surface normal direction is the Y direction, the curved surface tangent bearing is the Z direction

On par, Y X Z shaft definition, as shown in the diagram above, the Faubourg keel X direction for direction, the surface of the Line Direction, curved surface direction for Y Z direction for the tangential direction

X, y, z defined on the bars as shown above, along the keel to the x direction, the surface normal directions of the y direction, surface tangent orientation is the z-direction
