Textual representation in Rhapsody Systems Engineering 1.7.0

Hi, I'm trying to create a model in Rhapsody System Engineering (version 1.7.0) and it seems like I can't access the textual representation of the model.
I found it to create an element, but from the graphical representation I can't access the textual representation (SysML code) of an already existing element. 

How can I access it ?
Furthermore, I tried exporting the model but it seems like it isn't in there neither.
How can I extract the textual representation ?

Thank you for your help.
