Blender

[IndyJets]

Are there any good tutorials for Blender focused specifically on creating buildings to be converted to paper models? I don't need to deal with complex shapes (such as aircraft or characters), I'm just looking for some tips on creating a building with a moderately complex roof profile and wondering what considerations I might need to take into account.

Also what is the process involved in converting a 3D object into a paper model? Is there a built-in function in Blender that handles this? Also what format would the pattern be exported in? Are there settings for modeling scale and print resolution for the finished product?
