Ceiling requirements #1:
uThis program a
umes a constant ceiling heigtht throughout the entire
Vstructure to be analyzed.
If ceiling heigths vary, you must analyze each
Warea that varies from the co

Ystructure.
(Example:
A structure has a co
on ceiling heigth of 8 ft. through
X9 of it's 12 r
Two of the 'o

Utwo areas can be combined in one analysis.
The other r
