export from hypermesh to nastran with .dat

Good morning

I need to export my meshed model from Hypermesh to Nastran with a .dat file.
That was done by my colleague one year ago with an older version. Opening this old .dat file with notepad i found this:

 NASTRAN Input Deck Generated by HyperMesh Version  :14.0.0.88
$$ Generated using HyperMesh-Nastran Template Version : 14.0

So this export should be possible.

But now I'm using Hypermesh 2019 student but I can't find this function and I can't find a way to generate this export file .dat
