Making inside maps in VX

[Soupnazi]

Okay, so I downloaded the RPG maker VX trial, and am experimenting with it. However, I am unable to find the tile that allows you to make maps that look like they're inside. Now, I know there's an autotile in XP for it, so I searched for something like that. Nothing. Help!

Soupnazi, do you see the hedge tile? Right underneath that is a line of inner of inner walls, and ceilings. You should know what I'm talking about because under the inner walls/ceiling are the mountain, fire and ice caverns.

Oh, okay.

Hedge piece? And if so, how exactly do I use them?
