Creating a 3D castle model in Google Sketchup Part 1

So today I started making a 3D Model Castle in Google Sketchup. I'd like to make a 3D model like this to use in Anime Studio but the free version of Sketchup doesn't export to wavefront (obj.) format. To get that you need to pay out for the full pro version of Sketchup and I'm not planning to do that any time soon.

I don't know where this little project is gonna lead I just felt like making a 3D model. I may do updates on this as it becomes available or I may just quit the whole thing since I might not get any use out of it.
