Help with a project

I will soon be starting a project for my World History class. I am going to be modeling a medieval castle, and I will record a three dimensional tour of it.

I just began using blender about a week ago, so I really don’t know where to start. I believe that I can figure out how to actually model the castle, and whatever else needs modeling, but I don’t know the best way to go about it. So, here goes:

How big should I make the plane that I will be using for the ground? And how many times should it be subdivided?

Should I make the castle walls out of many smaller cubes, and just subdivide them, or should I make fewer, but larger, blocks?

How should I plan for the tour? Will I be able to go back and do the camera movements after I am done, or should I just do it as I go? Is their a faster way of moving the camera around than by using a frame-by-frame approach?

If there is a tutorial that I should be looking at, you can just direct me to that instead of answering all of these questions. There were so many that I really didn’t know which one to follow.

And I think that that is everything for now. Once I start the actual modeling, I will move it to the works in progress section, but since I have not yet begun, I thought that I should post it here.

You should probably do the camera movements after you’re done but I don’t think it makes a difference either way. The ground plane can be a single plane unless you want to make hills and mountains and stuff like that. Don’t make every little brick in your wall if thats what you meant just you a good brick texture with a normal map for your walls. Good luck with your project.

Thanks. I have watched Greybeard’s video tutorials since my post, and I have figured out the camera movements.
