Hi

Just to close this from my side - follow the video to do what you need.

Finally, have in mind you can not extrude a beam cross section (what you call profiles-'profiles I wanted, and from these profiles I can't make a surface extraction': you can not extrude these, these are only for assigning sections to beam element), you need to have a sketch as in the video, so you need to define those yourself manually in SC from scratch, and then which you can then finally extrude like in the video.
That is it really.

All the best
