MEP Family Standards: How Much LOD Is Enough, and Why Junk Families Break Systems
Families downloaded from uncontrolled sources are the most common silent cause of bloated MEP files and disconnected systems. Correct LOD and naming fix both.
View Range in Revit: Why Elements Disappear From the Plan After You Draw Them
