Skyrim Scale Model Question

I had originally posted this in General Forum, But thought 'I'll try here too'.
I am not sure where to post this, so it is in General. Please move this if it should be moved.
I am starting to get back into scale model building, currently getting model area whipped into shape. I like to scratch-build models (build from ground up not a kit).
Unfortunately I have trouble finding specific info when searching online. Thus, I am asking this Skyrim community for a bit of assistance. My question:

Does anyone know of a website that has 3D pictures of Skyrim assets that can zoom & rotate & that have some sort of scale measurements attached?

I play on 360, not computer. I can easily estimate sizes & get a scale, but like working with the actual numbers. Either Standard or Metric. I am not only looking for dwellings, items, and people; but also 'plots' of land. For instance a section of a mountain trail, the opening of a cave, the five most used sizes of boulders & trees. I like to do more of the diorama style models.
I will contact Bethesda when ready to begin if I haven't found anything. It will be a last chance sort of thing, due to trouble trying to get this info from companies in the past.

To add a question:
Does anyone know if I can get nexus mod stuff without having game on comp? I found out that I can pull out of that & put into 3ds max. I can get measurements that way but don't know if it'll work without game.
