Hiding objects not seen

Hello all,

I have a building where the roof material is modeled but only parts of that roof material is actually showing from the perspective that is being used.
Instead of going through, selecting each of the pieces and using the hide command is there a command to hide all objects that are not seen in a perspective?

From your description, I’m not sure if this is what you want but the SelVisible command will select all that is visible in a viewport. If you then invert the selection, you will have everything that is not seen in the view.

That worked perfectly thank you very much!
