    Two things:

    1.) Typically when maps are viewed from the outside (via noclip), brushes don't have any textures on their outer walls. Now is this just monotonous nodraw, or is there something else to it?

    2.) How do you do that thing that makes it so if you noclip out of the map, upon...reclipping... you're stuck, as if you're in a brush?

    1.its monotoneous nodraw as well as brushes that share a face with the skybox
    2.some maps have limitations on the height you can jump via playerclip-brushes, when you were noclip, and then un-noclipped inside one of those, you are stuck inside an invisible playerclip-brush

    not just monotoneous nodraw...
    any faces that are on the 'outside' of your map aren't included in the bsp.

    also:
    any faces that are covered with another face aren't included
    you should use no draws on areas that can't be seen, but still have to be inside the map.
    i.e. if you have a window to view an outside area, you might want some models in the view that don't have skybox versions, such as a shovel for example. what you'd do is set the wall on the side the player stands when looking out the window to have the texture you want, but the other side of the wall can be no-draw'd because the player will never see that face.
    another example of using nodraw is beneath/behind any displacements that mark the edge of a map, such as dirt/ground and cliffs.

    Isn't my entire map technically on the inside, since it's surrounded by my skybox?

    This doesn't apply to solid entities. You'll want to nodraw the inner faces of geometry constructions with nodraw for any solid entities.

    You did not just just enclose your map in one huge box with the skybox texture did you? You're only supposed to make a ceiling. Boxing it in will make your map perform horrible, and take ages to compile, as your entire map will probably be rendered whereever you are.

    A Skybox, in contrary to its name, is not a box. Its a texture that lets you view inside a virtual box.

    The way they explain it here: http://www.tutorialhero.com/click-37627-create_a_skybox_in_hammer.php
    is WRONG! it might work, but it is the wrong way.

    how you do do it, just make a ceiling where the sky is supposed to be, and don't have your level floating in a big box.

    so
