Namespace: Autodesk.Revit.DB Class: Floor

Floor.Create(Document, IList<CurveLoop>, ElementId, ElementId, Boolean, Line, Double)

Method

Description:
Creates a new instance of floor within the project.

Remarks:
To validate curve loop profile use BoundaryValidation. To get default floor type use GetDefaultFloorType(Document, Boolean).

Examples

/// The example below shows how to use Floor.Create method to create a new slopped floor on one level 
/// using a geometry profile and a floor type. 
/// In this sample, the geometry profile is a CurveLoop of lines, you can also use arcs, ellipses and splines.

Parameters

Parameter	Type	Description
document	Document	The document in which the new floor is created.
profile	IList	An array of planar curve loops that represent the profile of the floor.
floorTypeId	ElementId	Id of the floor type to be used by the new Floor.
levelId	ElementId	Id of the level on which the floor is to be placed.
isStructural	Boolean	True if new floor should be structural, false if architectural.
slopeArrow	Line	A line used to control the slope angle of the Floor. It must be horizontal. If slopeArrow is <span class="keyword"><span data-languagespecifictext="cpp=nullptr\|vb=Nothing\|nu=null" id="LST8FE5FCBD_5"></span></span>, the horizontal floor will be created.
slope	Double	The slope angle. If slopeArrow is <span class="keyword"><span data-languagespecifictext="cpp=nullptr\|vb=Nothing\|nu=null" id="LST8FE5FCBD_6"></span></span>, this parameter will be ignored.

Return Value

Type	Description
Floor	If successful a new floor object within the project.

Exceptions

Exception	Condition
ArgumentException	The ElementId levelId is not a Level. -or- The floorTypeId does not correspond to a FloorType. -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.
