Creating custom UDA and Property Sets for Tekla Structures in Grasshopper

Hello there, I am BIM student from Oslo and been recently introduced to Tekla Structures and Rhino Grasshopper scripting. I am currently trying to figure out fastest and most automated way to berich my modells with information.So basically I wish to create custom User Defined Attributes and/or Property Sets in Tekla modells that can later be exported with IFC files. Has anyone been working with something familiar of implementing information? Thank you in advance!

I know this is a late answer but I suggest you at first to create UDAs inside Tekla in order to understand the UDA logic then move to Grasshopper automation.

Here some useful links I encountered on my path:
