Ceiling Changes
Changes to ceilings may require some management of the lighting fixtures
in your model. Face-hosted lighting fixtures maintain their association with
the ceiling when there is a change in elevation, but you should also be
concerned with any lateral movement, especially with grid ceilings.
Lateral movement can have different effects on your lighting fixtures
depending on how the grid was placed into the model. Grids that are placed
by automatically locating the boundaries of a room do not affect your light
fixtures when they are moved laterally. This is true as long as the movement
does not cause your fixtures (which won't move laterally with the ceiling)
to be located outside the boundaries of the ceiling. If the architect deletes a
ceiling and then replaces it, your fixtures will become orphaned when you
gettheupdatedarchitecturalfile,andtheywillremainattheelevationofthe
original ceiling and will no longer respond to changes in the elevation of the
new ceiling. You will have to use the Pick New tool to associate the fixtures
with the new ceiling.
Ceilings that are created by sketching the shape of the ceiling have a
different effect on your fixtures when moved laterally. If the entire ceiling is
moved,yourlightfixtureswillremainintheirlocationrelativetotheceiling.
If a boundary of the ceiling is edited by dragging it to a new location while
in sketch mode, your fixtures will remain where they are located; however,
anyattemptstoplacenewfixturesintotheceilingmaycausethemtoappear
outside the host, and you will receive a warning indicating that the fixture
has no host. You can use the Pick New tool then to place the fixture into the
ceiling.
Because ceilings tend to move around quite a bit in the early stages of
a design, you may want to consider hosting your lighting fixtures to a
reference plane until the major changes have settled down. At that point,
you could move your fixtures into the ceilings by using the Pick New tool.
In the meantime, encourage the architects you work with to avoid deleting
ceilings and simply alter the ones that exist, when possible.
