	Document^ document,

	ElementId^ floorTypeId, 
	ElementId^ levelId,

)

Parameters

document
Type: Autodesk.Revit.DB Document
The document in which the new floor is created.
profile
Type: System.Collections.Generic IList CurveLoop
An array of planar curve loops that represent the profile of the floor.
floorTypeId
Type: Autodesk.Revit.DB ElementId
Id of the floor type to be used by the new Floor.
levelId
Type: Autodesk.Revit.DB ElementId
Id of the level on which the floor is to be placed.
isStructural
Type: System Boolean
True if new floor should be structural, false if architectural.
slopeArrow
Type: Autodesk.Revit.DB Line
A line used to control the slope angle of the Floor. It must be horizontal. If slopeArrow is a null reference ( Nothing in Visual Basic) , the horizontal floor will be created.
slope
Type: System Double
The slope angle. If slopeArrow is a null reference ( Nothing in Visual Basic) , this parameter will be ignored.

Return Value

If successful a new floor object within the project.

Remarks

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

Examples

Copy C# 
/// 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.
Floor CreateSlopedFloor(Document document, Level level)
{
   // Get a floor type for floor creation
   ElementId floorTypeId = Floor.GetDefaultFloorType(document, false);

   // Build a floor profile for the floor creation
   XYZ first = new XYZ(0, 0, 0);
   XYZ second = new XYZ(20, 0, 0);
   XYZ third = new XYZ(20, 20, 0);
   XYZ fourth = new XYZ(0, 20, 0);
   CurveLoop profile = new CurveLoop();
   profile.Append(Line.CreateBound(first, second));
   profile.Append(Line.CreateBound(second, third));
   profile.Append(Line.CreateBound(third, fourth));
   profile.Append(Line.CreateBound(fourth, first));

   Line slopeArrow = Line.CreateBound(new XYZ(10, 10, 0), new XYZ(11, 10, 0));
   return Floor.Create(document, new List<CurveLoop> { profile }, floorTypeId, level.Id, true, slopeArrow, Math.PI / 2);
}

   Dim second As XYZ = New XYZ(20, 0, 0)
   Dim third As XYZ = New XYZ(20, 20, 0)
   Dim fourth As XYZ = New XYZ(0, 20, 0)
   Dim profile As CurveLoop = New CurveLoop()
   profile.Append(Line.CreateBound(first, second))
   profile.Append(Line.CreateBound(second, third))
   profile.Append(Line.CreateBound(third, fourth))

   Dim slopeArrow As Line = Line.CreateBound(New XYZ(10, 10, 0), New XYZ(11, 10, 0))
   Return Floor.Create(document, New List(Of CurveLoop) From {

Exceptions

Exception Condition
Autodesk.Revit.Exceptions 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.
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.
