The best way to model Sims is to build them a white floor that isn't distracting. Then you can use it and a nice pose to screenshot your creation you are modeling and use it to get people to download your creation.
Unless there is a mod to change this, you cannot make your sim just sit on the floor. The "Hang Out" option will sit them on the floor but that is two sims "hanging out" and talking on the floor...they do not just idly sit there.
You can't build above the 5th floor.
No, your sims can only have one floor in the Sims 2 PlayStation version. If you want to have your sims live in a two floor house, or even in a mansion, you can buy the Sims 2 on PC and eplore better advantages of the game.
Theres a lot of Sims on ps2 like: The Sims The Sims Bustin' Out The Sims 2 The Sims 2 Pets The Sims Castaway I'd say Bustin' Out is the best.
All of them end up giving you the same amount of money at level 9 or 10
You have to go to the build section and buy stairs and then you have to make a floor.
