Partition Walls Under Suspended Grid Ceiling?

[cwrm74]

I am modeling a warehouse with 28 ft eaves. One corner of the warehouse has office space, which is bounded by two 28 ft exterior walls and two full height (28 to 30 ft) interior walls facing the open warehouse area.

 

The office space has a suspended tile grid ceiling at 9'9". I've watched the Chief tutorial on modeling a suspended grid ceiling, and that works fine. However, they only model a single large room. The space I am modeling has fully enclosed offices under a continuous grid ceiling.

 

How can I add floor-to-ceiling office partition walls under the suspended ceiling, so that the ceiling grid is continuous across the entire office space? I tried using half walls (i.e., solid railings), but if doors are placed in those, there is no header over the door.

Great idea - looks like that should work perfectly! Thank you.
