Map Making ~ Noob Questions :3

[EmptyHabits]

I'm making a map for my pack I'm hoping to create. I've been playing around with Map Maker and meshes/materials/objects... Blah. Blah. Blah. And I want my map to have boundaries. Meaning when a member is in the map, I don't want them to be able to run to the complete edge of the map and see nothing passed it. So I know how to set boundaries and how to work with that, but I'm confused on how to tell where to put objects. Take a cave for example. I want to place it right before the boundary, and the entire cave is accessible but you can only go an inch behind it. I don't want to place objects where members cannot reach... Is there any way I can tell where I'm placing my object? Say my boundary right now is 500. I want to place a cave just a few inches away from it so members can go inside. Is there a scale where I can see when I'm placing objects? I dunno if I explained this very well, but I think I did. XD To put it short... How can I tell if an object is passing a boundary line or not?? Thank you in advance!

It's a simple task, but asinine. You test the map (where you run about as the default lion), and check where the boundary is. If you can memorize where it is, place an object where ever you desire, and simply test the map again to check if you placed it where you want.
It gets annoying and somewhat takes a little more time, but it's the only solution I believe.
