im From Brazil, and here we use Beams/profiles based on "açominas"
theres a way to edit profiles, or add new ones
im new on this software.
I would recommend downloading the revit extensions from the subscription centre and use the generate content tool.
if you need a "quick" way, you can do a user profile, by drawing out the profile, then converting it. When you convert it, it will prompt whether you want it local or not, if you make it local, it's for this drawing only. Once you create it, it will be in your profile list.
