I am possibly going to resuse an existing area without much structural alteration. Sim has suggested to me flipping it horizontally to make it look more different, and thinks DLTCEP might have a feature where you can correspondingly flip the .WED. Thinking about it, you'd need to flip some stuff in the .ARE too...
Anyhow, I couldn't find it in DLTCEP. Does anyone know if I have been looking in all the wrong places, or alternatively has someone perhaps got some tp2 code they've used for a similar purpose they might post?
