What this program can do.
create and place stackable peices
overlap peices
create the "pool floating" effect
create "bridge rails"
add peices to an aready full park
What this program can't do
although it can creat stackabe peices it can't actually stack them for you
say for instance, you create a stackable quater pipe, you will still need to
use the in game editor to place whatever it is you'd like on top of the quarter pipe
hopefully i'll be able to add support for stacking peices in a future version.
