you mean you have a ceiling grid layout that is true-size and true-shape? Mean it's ... un-bent or un-folded?
If so, then yes, there's no stock way to transfer that onto a curved surface in Autocad.
If you have a reflected ceiling plan that is a true plan, meaning it's not true size, and has distortion due to looking at a slanted surface in plan view... then there's hope.
Let me know which case is true and if the latter is so... how do you want it transfered onto the 3d ceiling? What type of object is the ceiling model?
If it's the first case, then yea, you'd need something automated and I don't even know how the heck anyone would even START progarmming that... if you find that, I'd -love- to see the principles of that routine... that'd be some awesome programmatic trig.
