hi all, i haven't ran into this before. i hit the heating and cooling loads button to do a preliminary check, and every single space in the building i'm working on has this error "Space 02 is not upper bounded by a roof, ceiling or floor element. This can result in incorrect adjacencies and voids in the analytical model. Please ensure that Upper Limit and Limit Offset for Space 02 is set correctly." i checked and all the spaces are set to bottom limit equal to the level they are on, and upper limit is set to the floor above. then i checked and the ceilings all show room bounding. but if i look at a section view the spaces go right to the floor above, instead of stopping at the ceiling. any thoughts. i can't even send this out as a gbxml until i fix this problem.

Rooms and spaces are not the same object right. A room is architectural and a space is MEP. You can convert linked in rooms to local MEP spaces.

i know that rooms and spaces are not the same. i've been using Revit MEP since 2008. but i've never had this problem on more than one space. they are all spaces and not rooms. i just can't figure out why it won't recognize the upper bounded ceilings.

i found the problem. now that all 3 disaplines are in one software, some things act different. i created spaces not rooms. but i found the answer in the Architect tab. thanks to the help feature. 

When the Areas and Volumes option is selected in the Areas and Volumes Computations dialog (Architect tabRoom & Area panel drop-downArea and Volume Computations), additional room-bounding components may determine the vertical extent for spaces, and affect the volume computations. With Areas and Volumes selected, space boundaries snap to roofs and ceilings. Snapping occurs if Areas and Volumes is selected and the vertical extent of the space intersects one of these room-bounding components. The base and vertical extent properties for a space are not changed by the Areas and Volumes setting.

and just that easy, the problem is gone.

Inner space is not surrounded by outer space with higher height.
