Diffcheck moves all ceiling diffusers vertically into the ceiling grid. DiffCheck also checks all ceiling diffusers for conflicts with lights and sprinklers.

General Usage Instructions

DiffCheck is incredibly easy to use.  The diffcheck menu has 2 options: adjust the height of all diffusers to lay in the associated ceiling, and run a clash report on all interfering objects (lights, sprinkler heads etc.).
