family profiles upn coupled

[oppo75]

Hello everyone, I have a problem with revit structure 2010. in particular I can not create a family with coupled upn profiles, because in the library there is the double c one made with profiles c that I never used. I basically want to change the library from here profiles with that of the upn but I can't.
thanks for the answer

I have never used recit structure.
I have not understood well:
Do you want to change the family in the project?
Want to upload a family of upn profiles?
Can't make the family?

Hello, frank, thank you for answering me.
then, what I would like is to have in the revit library a family for structural beams in composite steel type: 2 hea, 2 heb, 2 upn, etc. because in the folder structural-steel beams there are only two families of coupled beams, those with profiles to l and c.
I tried, starting from family 2 c coupled, to create family 2 upn coupled but....not cable a spider from the hole. i.e. I managed to make a structural beam with a profile coupled upn (e.g. upn 300) but if in a second moment I want to change the profile I do not open a mask with already all the sections loaded and I have to remake the profile, extrude it, etc... maybe it is easier to make than to say.... I tried even if in the web there were already beams with profiles coupled... but I did not find it...
