Array with scene.

Hello,
I created an array made of 12 LPDA antenna in order to simulate an Instrument Landing System (ILS) facility, cf. "Array.cfx".
To do so, I created one LPDA antenna that I replicated 12 times with the tool "Construct/Structures/Planes/arrays/Custom Array Element" :

I would like now to create other objects that will be illuminated by this array.
But when I try to add for instance a single cube somewhere ("Construct/Cuboid"), CADFEKO creates not 1 but 12 times this cube, apparently related to the 12 antenna of the array.
In the following picture, I would like to see the interaction between the array and a single cube, not 12 cubes :

Since I created the array, any other single object that I try to add to the scene is in fact added 12 times, which is not my goal.
Would someone know how to add unique objects ?
Thank you in advance.

    Hi,

    It will be good if you can use Feko antenna array script (that is available in Application Macro) to generate the array and then create the cube. Here is the screen shot that I generated the LPDA array with cube using Antenna Array Script.

    Here is the link about FEKO (Antenna Component Library and Array tool)

    I hope this should help to resolve this issue. 

    Meanwhile, I will review your model and get back to you on the issue. 

    Thanks!

    Hi Raja,
    Thank you for your help, which is indeed a way of solving my problem.
    But my LPDA is customised and does not correspond to the standard Feko model.
    I finally solved my problem by re-generating my network by hand (antenna by antenna), which is a bit tedious but works.
    Thanks for all your help!
