Hello all, first post here and relatively new using Revit. I have started a project and am trying to create some custom dormer windows for it, so I created it as a family and started playing with it somewhat to make parts of it parametric (frame size, opening dimensions, etc). It's not fully, but it was more for my own practice than anything as the window really will be only 1 size. Anyway, I finally finished it and imported it into the Revit file and placed it in a generic 6" stud wall and all was o-so fine. However, being a glutton for punishment, I decided to put it into an already existing 8" cmu wall, and for whatever reason, Revit couldn't place it in the CMU wall at all. I thought it might be the way the walls structure was done, so I changed it to another stud wall that I had created (5/8" finishes on either side of a 6" metal stud, all within the core of the wall structure) and bammo, it placed the window. So, for whatever reason, it so far has placed it in 3 differing walls, all of stud-type construction (thickest wall was the 5/8" X2 + 6" stud = 7-1/4" but will not cut thru any CMU wall (either generic 8" wall or any of my created CMU walls). What am I doing wrong? I've attached the dormer window family I created - any help would be appreciated. Please ignore the childish attempts on it at automating it as I'm still learning. Thanks in advance for any help anyone can provide.

The wall thickness is giving you problems. You really have to be careful when creating hosted families. Revit elements associate with revit elements around them. In wall cases, it may not be the surface of the wall but the centerline. When the wall thickness is flexed, the family falls apart. I like to add a reference plane well away from the face of my wall and build my wall around that. I then add a dimension from that plane to the face of the wall and adjust where the whole unit is finally placed using that dimension. Obviously, if this dimension is parametric, you can type or instance locate your family relative to the wall face.

I think I may have discovered the problem. In my inexperience, I placed a reference plane and locked it to the outside face of the wall and built my window off of that. From my further dives into family-making for this project, I've learned that you can reference the front face of the wall and and still make it parametric. This rouge plane may be the cause of it not being able to punch through walls that are thicker than the reference wall in the original family. I may experiment with it now that I have a breather from my original deadline. Thanks for the response!
