3D Model/Map of buildings

Hi,

I've been asked to create a model of an airport. Very basic. No textures and only simple shapes to represent check in zones, stairs, restaurants etc. It needs to be able to animate from floor to floor in birds eye view and to the outside of the building at an eye level view. It will be an annotated clip that plays following a persons movements. It needs to be incorporated into an adobe air application.

I'm not sure even what software i should use for this. Please bear in mind i don't have any experience with 3D packages like 3DS Max. I suppose its possible in Flash Professional but can imagine drawing it all being a bit of a pain, is there something out there more suited?

How would you recommend going about this?

If you want to use boxes (or other simple extruded 3d shapes) as buildings and create a spline with camera going from one point to other you can use following software:

You can also add some camera interaction - to give user possibility to look around a bit.
