Hello all,

I'm fairly new to revit and i'm trying to use the section box tool in the properties menu to cut the building in pieces and get a better look.

I'm in a 3-d view and when i check the box that says "section box", nothing happens. On other projects, when i did this, a purple box would surround the building and i could cut the building as i wished. However, for some reason its not having an effect. I've tried duplicating new 3-d views and creating brand new ones but it doesn't do anything. Any ideas? Any help is appreciated, thanks

Rob
