pool to sfioro

[Eerene]

Hello, I have a problem with the modeling of an infinity pool. I do not know how to insert the elements of the grid and perimeter profile. for the metal profile I imagined having to create a family (not being already available the right one) to insert it in the project but "banally" I do not know with which command to insert it. Can a profile be inserted without being associated with another object?
thanks to anyone who will give me some time!

you can use a generic wall-based model. after the creation of the family, assign it to a category
