Ceiling Grid layout different when shown on floor plan

[Anonymous]

my 600x600 grid when shown on a floor plan (by raising the view range) is a different pattern when shown on on RCP.

all ceilings on the project are a direct copy up, so it isnt looking else where for a ceiling layout.

any help appreciated

The floor plan looks down to the pattern on top surface of the ceiling, the ceiling plan looks up to the pattern at the bottom surface of the ceiling. Those pattern alignment are independent. You can manusly align them so they match.
