Hey,
I am very new to Away3D. I have to create a 3D map of a floor of a building and make path and a character animation from source to destination points. I have to show the map in different orientations. Can you please let me know if its possible in Away3D and if yes, from where should I start?

Sure its possible. Map and Path is the same in 2d and 3d so its not best place to ask:). Try to find solution on some game developer forums. Than if you have path algoritm working you can display it in 3D.

cheers
