Software program like as NEC can do 3D modeling. It may not really consider the native pattern documents provided, nevertheless.
Antenna analysis software by Roy Lewallen. Above: Screen shots from several EZNEC v. 6.0 displays.Right: 3D far field pattern, with 2D elevation 'slice' highlighted. Any azimuth or elevation slice can be highlighted. Center: View Antenna display, showing the 'wires' making up the model of the five-element beam, with currents and 2D slice superimposed to show orientation.
I put on't think it will become of very much practical make use of to you in this case.
Any antenna't radiation design is generally measured using an approximation of 'free of charge room,' that is, no close to objects. Even if scored on an antenna range, the design is basically theoretical. When installed, every object near the antenna (wall space, ceilings, cables, physiques, and reflections fróm all those objects) will modify the pattern significantly.

Generally, the just time such a pattern would be of use is definitely if you had been doing long-distance links with two antennas mounted high and in the clear. Even after that, the just really useful value would end up being the peak gain.
