Parameters

document
Type: Autodesk.Revit.DB Document
Document to which new area load will be added.
hostElemId
Type: Autodesk.Revit.DB ElementId
The analytical surface host element id for the area Load.
loops
Type: System.Collections.Generic IList CurveLoop
The loops that define geometry of the area load. The curve loop collection should contains a closed loops consisting of lines.
forceVectors
Type: System.Collections.Generic IList XYZ
The array of force vectors applied to the maximum three reference point of the area load.
refPointCurveIndexes
Type: System.Collections.Generic IList Int32
The array of maximum three curve indexes on which reference points should be placed on.
refPointCurveEnds
Type: System.Collections.Generic IList Int32
The array of maximum three curve ends indicating where reference points should be placed on. The array can have only 0 or 1 values, which means 0 - curve start point, 1 - curve end point.
symbol
Type: Autodesk.Revit.DB.Structure AreaLoadType
The symbol of the AreaLoad. Set a null reference ( Nothing in Visual Basic) to use default type.

Return Value

If successful, returns an object of the newly created AreaLoad. a null reference ( Nothing in Visual Basic) is returned if the operation fails.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException hostElemId is not permitted for this type of load. -or- One of the following requirements is not satisfied : - curve loops loops are not planar - curve loops loops are self-intersecting - curve loops loops contains zero length curves -or- Thrown when force vector is equal zero.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was null
Autodesk.Revit.Exceptions ArgumentsInconsistentException Thrown if the host element id is a Curved Panel.
Autodesk.Revit.Exceptions InvalidOperationException Thrown if type could not be set for newly created area load.
