<div>Hi All,</div>
<div> </div>
<div>I am trying to model hexagonal shape collimator in rectangular array.</div>
<div> </div>
<div>For this aim , I am using cubic array and linear array repeating together.</div>
<div> </div>
<div>When I do this my final collimator design becomes square or rectangular shape , because I would like to repeat my hexagonals in a rectangular array.</div>
<div> </div>
<div>How does this repeating mechanism working?</div>
<div> </div>
<div>According to this reference it is rectangular. Am I right?</div>
<div> </div>
