Yes i have used the search bar, and i have not found the answer to my question!mg: I don't have the Mythic Map Pack yet, but im just filled with ideas on what to make as soon as i get it, as i'm sure every other forger here is... Anyway back to my question, :frustrated:Is there a item on Sandbox similar to the door on Foundry that can be used for Geo-merging?
No, and I'm quite frankly amazed you didn't find any information on a search for Sandbox geomerging. You'll have to manually interlock an item to push other items into the ground/wall, there are no items that interlock on their own like doors did. Just measure it out in steps and it is more accurate than doors ever were.
check the forging 101 thread for merging immovable objects with map geometry and use the first method it offers
