How to merge adjacent cubes I am trying to develop a small dungeon. My idea to to generate it programmatically and refine it by hand. Floors and walls are all cubes.

This is the file. I want to do two things:


Merge Wall_1_Room04 with Wall_1_Room05
Merge the wall obtained in the previous step with Wall_7_Room04


I looked for a solution, but I was not able to find it. So I have a few questions for you:


Is is possible to do it? If yes, how?
Is the fact that every Wall has a child cube a limitation?
What you need to do is select Wall_1_Room04, then select Wall_1_Room05. once they are both selected, with Wall_1_Room05 being the active object press Ctrl+J. This will join the walls, the origin will be at the location of Wall_1_Room05's previous origin.

After that, tab into edit mode, select all and press Ctrl+V > Remove doubles. repeat the process for Wall_7_Room_04.
