Floor.Create

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).

Overloads (2):

Create(Document,IList[CurveLoop],ElementId,ElementId)

Create(Document,IList[CurveLoop],ElementId,ElementId,Boolean,Line,Double)

	Document document,
	IList<CurveLoop> profile,
	ElementId floorTypeId,

Autodesk.Revit.DB.Document

document

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

profile

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

floorTypeId

Id of the floor type to be used by the new Floor.
Autodesk.Revit.DB.ElementId

levelId

Id of the level on which the floor is to be placed.
Boolean

isStructural

True if new floor should be structural, false if architectural.
Autodesk.Revit.DB.Line

slopeArrow

A line used to control the slope angle of the Floor. It must be horizontal. If slopeArrow is nulla null reference (Nothing in Visual Basic), the horizontal floor will be created.
Double

slope

The slope angle. If slopeArrow is nulla null reference (Nothing in Visual Basic), this parameter will be ignored.

Return Value Floor If successful a new floor object within the project.

/// 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.
