Autodesk.Revit.DB.Document

document

The document in which the new ceiling is created.
IList<CurveLoop>

curveLoops

An array of planar curve loops that represent the profile of the ceiling.
Autodesk.Revit.DB.ElementId

ceilingTypeId

Id of the ceiling type to be used by the new ceiling. If InvalidElementId is passed, the default type will be used.
Autodesk.Revit.DB.ElementId

levelId

Id of the level on which the ceiling is to be placed.
Autodesk.Revit.DB.Line

slopeArrow

A line used to control the slope angle of the Ceiling. It must be horizontal.
Double

slope

The slope angle.

Return Value Ceiling If successful a new ceiling object within the project.

Autodesk.Revit.Exceptions.ArgumentException

The ElementId levelId is not a Level. -or- The ElementId ceilingTypeId does not correspond to a CeilingType. -or- The input curve loops cannot compose a valid boundary, that means: the "curveLoops" collection is empty; or some curve loops intersect with each other; or each curve loop is not closed individually; or each curve loop is not planar; or each curve loop is not in a plane parallel to the horizontal(XY) plane; or input curves contain at least one helical curve. -or- The slopeArrow must be a horizontal line. -or- Input curves build invalid sketch. -or- Failed to create curve elements.
Autodesk.Revit.Exceptions.ArgumentNullException

A non-optional argument was null
Autodesk.Revit.Exceptions.InvalidOperationException

Cannot generate a sketch. -or- Failed to create new element.
Autodesk.Revit.Exceptions.ModificationForbiddenException

The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
Autodesk.Revit.Exceptions.ModificationOutsideTransactionException

The document has no open transaction.
