johnny 458 Posted November 8, 2020 Every so often windows refuse to mull together correctly. Here is a recent example on a current project. Does anyone know what setting might cause this? Here is the sectioned area with the windows and some pictures. Thanks for any help.mull_issue.plan mull_issue.zip Share this post Link to post Share on other sites

I'd say not offset from the outside casing...but i know there is typically a small offset chief shows (which i'm not sure of the logic there), but what I have now is nearly void of material thickness in-between the upper and lower window. On your blue example to the right it does appear less drastic than the left...but when I mull the top and bottom window in the same file i get the same error. Are you doing anything to get a different result? Share this post Link to post Share on other sites

I guess in my mind I was mulling to get the casing to work, so I wasn't imagining this to be a mullion - but obviously by the operation that is exactly how Chief views it. This was very helpful.
