Sample family-planning design form
Creating geometry in the Ref. Level view places it at the reference level. The
reference level in a family is a placeholder for the project level when you
insert the family into a project. That is how a light fixture inserted on the
second level of your project is associated with the second level. Therefore,
the elevation or offset that you apply to the fixture is relative to the level at
which it is placed. If you are creating a nonhosted lighting fixture that you
want at a specific elevation when you insert the family, you can build the
geometry at the desired elevation. This has the potential to cause confusion
when using the Offset parameter, so a best practice is to use the reference
level.
