Syntax

C#
public static Floor Create( Document document, IList<CurveLoop> profile, ElementId floorTypeId, ElementId levelId, bool isStructural, Line slopeArrow, double slope )

Visual Basic
Public Shared Function Create ( _ document As Document, _ profile As IList(Of CurveLoop), _ floorTypeId As ElementId, _ levelId As ElementId, _ isStructural As Boolean, _ slopeArrow As Line, _ slope As Double _ ) As Floor

Visual Basic

Public Shared Function Create ( _
	document As Document, _
	profile As IList(Of CurveLoop), _
	floorTypeId As ElementId, _
	levelId As ElementId, _
	isStructural As Boolean, _
	slopeArrow As Line, _
	slope As Double _
) As Floor

Visual C++
public: static Floor^ Create( Document^ document, IList<CurveLoop^>^ profile, ElementId^ floorTypeId, ElementId^ levelId, bool isStructural, Line^ slopeArrow, double slope )

Parameters

document: Type: Autodesk.Revit.DB..::..Document
The document in which the new floor is created.

profile: Type: System.Collections.Generic..::..IList<(Of <(<'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 nullNothingnullptra null reference (Nothing in Visual Basic), the horizontal floor will be created.

slope: Type: System..::..Double
The slope angle. If slopeArrow is nullNothingnullptra 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

CopyC#

/// 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);
