How to disassemble optimized beam cross section


I hope someone can help me.

I have created two models with multi span beams - SLS and ULS loads.
(I made two models, because for SLS I want to optimize mainly for deflection, while ULS is moment resistance).

End result is I have received two different necessary cross sections.
I want to compare, which one is the decisive one.

In order to do that, I thought I’ll disassemble the model and elements and get the info about sections used, however I have difficulty doing it.

Just disassembling the model, cross section output gives me the default cross section used before optimization, so that isn’t usable.

Meanwhile beam output contains the necessary optimized cross section.
So I tried disassembling elements, but I have difficulty in order to do it correctly.

The error is
“1. Solution exception:Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index”

How should it be connected correctly in order to disassemble beam used in optimized model?

Thank you for your time and help!

Upon further investigation, this seems like a bug.

For other people, using the same definition, it works as intended.
