Catia V5 Structure Design in Catia 3DExperience

Hi,

how can I make basic structure design as it was in Catia V5 - youtube example but in 3DExperience Catia? I observed app Structure design but I didnt find any information how to make "frames" in this version. (btw I use 3DExp. 2019x). I didnt find any tutorial in google...

Thanks.
