EXPORT ASSEMBLY SEQUENCE

Hello everybody,

I'd like to implement an algorithm by means of NX Open API to store into an XML file the assembly sequence that I created with features provided by NX. In particular, I'd like to:

Get movement (path in terms of position and orientation) for each component of the assembly over time (for example every second)
Store this data into the XML file for further use.
Unfortunately, I tried to use "Journal Recording" to understand the commands used by NX, but it doesn't record anything. So I think there is no way to use the journal for this scope.
I need some suggestions to try to solve this problem.

Thank you for your help.
