Hello ! I've started with Sketchup some days ago and absolutely love it !

But I need some help to find something in the 3D Galerie:
I'm searching for an standard art Galerie, because I want to present an Art Installation/ Projekt, and need for this a simple "showroom".

Furthermore I wanted to ask if you can give me a tipp where I can find People in the 3D Galerie, so that I can place them in the "showroom" as visitors of the Exhibit.
I would be veryvery greatfull about concrete links !
Thank you very much !*
