I have found this very nice 3d model of a city : tf3dm.com/3d-model/paris-33983.html
However the model is very big and has lots of streets, buildings etc. whereas I only need a small part of it. 3-4 blocks are enough for me, and I want to remove the rest of the model. How can I do that?

I cannot select with mouse because objects are grouped in a strange way, i.e. all the trees are a group, all the roofs are a group etc.

I'm using Maya but I'm ok with any type of solution with Blender, SketchUp, MeshLab, SolidWorks or anything. Just tell me a way to select and remove parts of this model.

Thanks for any help!
