Syntax

public static Ceiling Create(
	Document document,
	IList<CurveLoop> curveLoops,
	ElementId ceilingTypeId,
	ElementId levelId,
	Line slopeArrow,

Parameters

document Document: The document in which the new ceiling is created.
curveLoops IListCurveLoop: An array of planar curve loops that represent the profile of the ceiling.
ceilingTypeId ElementId: Id of the ceiling type to be used by the new ceiling. If InvalidElementId is passed, the default type will be used.
levelId ElementId: Id of the level on which the ceiling is to be placed.
slopeArrow Line: A line used to control the slope angle of the Ceiling. It must be horizontal.
slope Double: The slope angle.

Return Value

Ceiling
If successful a new ceiling object within the project.

Exceptions

Exception	Condition
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.
ArgumentNullException	A non-optional argument was null
InvalidOperationException	Cannot generate a sketch. -or- Failed to create new element.
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.
ModificationOutsideTransactionException	The document has no open transaction.

Remarks

To validate curve loop profile use BoundaryValidation.
