Wall & Ceiling Constraint

[ashiq_ansari]

In Revit 2022 I created Wall & Ceiling model & then later I increased room size so I moved Wall accordingly, But While moving wall, Ceiling also extended its boundary with it without required for boundary edit later on
(NOTE: NO ATTACH BOUNDARY OR CONSTRAINTS PROVIDED)
Please Suggest the concept how it works ?

That is how it behaves when you use Automatic Ceiling. It uses the walls to generate itself and it assumes that it should remain bound to these walls. If you wísh that to work otherwise, then create the ceiling by sketch
