new at this. trying to make a new map based off map #3697

[Quess]

Hello there! I've been browsing some forums and managed to successfully copy map #3697 into my editor. However, I'm having trouble removing the existing units so I can start creating my own map with the scripts. I'm guessing that I need to clear something in the mod Rebuild, but I'm not quite sure how to go about it.

Any hints, tips, or tricks you have to offer would be greatly appreciated. I was really hoping to use map #3697 as a foundation for my own creation. I love the relaxing gameplay of assisting and seeing everything come to life.
