3D buoys

OrcaFlex 3D buoys are simplified point elements with only the three translational degrees of freedom, $X$, $Y$ and $Z$. They do not rotate, but remain aligned with the global axes $\GXYZ$. They have no rotational properties, and moments on the buoy are ignored. They should therefore be used only where these limitations are unimportant.

3D buoys are able to float part-submerged at the surface, and may also be used independently, with no other objects connected. Although they are much less sophisticated than 6D buoys, 3D buoys are correspondingly easier to use and are convenient for modelling buoys at line junctions, for example.
