DONE button Hensin HUD

IN the manual it tells little about the last buttons in the Hensin HUD. I have build, fixed and edited the building since after the generator builded the building. Now I am done and pleased wwith the building as it is.

What happens when i push the DONE button. The scripts will be removed, ok - But does it change everything i have done with the building after i used the Build command? will it effect the building visible in any way when i push that button?
