I just want jump in here and emphasize the point Toan made, because it is a critically important to understand. The Wall Location Lines need to be carefully considered and decided upon – BEFORE dimensioning and BEFORE constraining other elements to them dimensionally (e.g. door, windows, other walls). If you don’t, you will have a mess of fires to deal with down the road as the project builds. I promise.
You’ve already experienced one of those fires; a small one. Your simple modification to one wall’s façade or wall finish has moved the location of a few other walls locations in your project. You’re lucky. Imagine the cascade of fires that it could have caused if all your walls were constrained together dimensionally – and each one was flexing differently. Then that one little change could have then affected the location of every single wall and hosted element in the project.
My suggestion: before going any further, check and correct if necessary, all your wall location lines. Make sure that they flex correctly in relationship to their location lines. Also, when you do place dimensions, pull them to and from the wall location lines. Wall Location Line = Dimension Line Origin. If you typically pull dimensions from Faces of Core (as we do), then have your wall location lines set to Core Face: Interior, or Core Face: Exterior.
Good Luck
