unpacking buildings?

Hi I'm absolutely new to modding. What I want to do is I want to be able to find a way of getting the buildings so I can edit them in the 3d software that I have. ( I use blender) If there is anything anyone can tell me abou t this it will be greatly appreciated.

Unfortunately, you can't do that. The buildings share the same problems as the meshes insofar as they're using proprietary software somewhere. So we'll have to wait for CA to release an exporter tool for it.
