on the south wall in foundry (the one with the fans) I'm trying to put a bridge extending from the corner but the problem is that the big doors make it break away from the wall and create a gap. does any one have a suggestion to what I should do? is it possible to geo-merge the bridge with the wall? help is appreciated.
It is indeed possible to geomerge into that wall. To do so with a bridge, I suggest you frame it on all sides with teleporters and use doors to push into the wall as you usually would with a standard merge. For this particular merge you're going to have one part of the bridge merging earlier than other parts, because of the doors. This means that the bridge will have a tendency to twist at an angle, when you want it to go in straight. Start with supporting underneath the bridge at the desired height with tele's. If you don't want to have to save quit as much, and don't mind losing out on a more specific custom height and more reliable merge, stack underneath instead, with boxes and walls to the desired level. Once you've done that, frame the ends and top of the bridge with teleporters. Then, to merge in level and get around the problem of having to merge in at different depths, place your doors into the bridge all the way along its length. Make sure they are placed into the bridge the same distance, and make sure they are standing upright with plenty of room above and below so the bridge doesn't slip up or down to avoid merging in the other direction. Hopefully that makes some sense, and all the best getting that pesky bridge into the wall nicely.
