Fulcrum (6.3.2): zoom-out does not show entire model

[Fabian Sommer]

I'm using Fulcrum from SCALE 6.3.2, mostly with csas5 input files of ICSBEP benchmarks.

With some of my models, the zoom-out option does not show the entire model (in x-z and y-z representation). It only shows the maximum x-extention (or y-extension), not the z-extension. It's the same result, wether I drag the mouse from bottom right to top left, or put 1 as zoom factor. 

If I put 0.5 as zoom factor, I see everything. However, for a good workflow, I would like to use the mouse-drag option.

In x-y representation it works fine.

My models are calculated without error or warning, so there is no major flaw.

I'm not entirely sure, in which cases this is happening, but I have the suspiccion it happens, if I have at least three nested arrays.

Does anyone have an idea, where the problem might be and how to solve it?
