hi chris,

all plans and rcp's are cut at 48" aff (above finish floor) at the CATIA
model.  this is standard practice for architects.  plans are cut at 48"
looking down; rcp's are cut at 48" looking up.  (i know that's probably
obvious but..)

everything is cut at this height without exception.  then items beyond
which is visible is projected.  all items are then measured to the first
"visible" surface at the plane of projection.  so some of the upper
ceilings which lean out of view will not be visible in the rcp.  as
well, if certain surfaces need to be extracted as a whole plane (some
odd ceiling somewhere) the info will have to be extracted out of CATIA
separately.  we did this, for example, for the back wall of the helmet
to extract the correct flattened geometry information for the millworker
(strangely, SKANSKA never asked for the info for their drywall guys....?).

hope that helps.
