Parameters
- aDoc
 -  Type:  Autodesk.Revit.DB Document  
Document to which new line load will be added. 
- host
 -  Type:  Autodesk.Revit.DB.Structure AnalyticalModelSurface  
The analytical model surface host element for the line Load. 
- curveIndex
 -  Type:  System Int32  
The index of a curve in analytical surface element starting from 0. Use [!:Autodesk::Revit::DB::Structure::AnalyticalModelSurface::GetLoops(Autodesk::Revit::DB::Structure::AnalyticalLoopType::All)] method to obtain appropriate curve index. Curve index has a unique value in analytical surface element even if it contains more than one loop. The index should be obtain by iteration through all curves in all loops. 
- forceVector1
 -  Type:  Autodesk.Revit.DB XYZ  
The applied 3d force vector. 
- momentVector1
 -  Type:  Autodesk.Revit.DB XYZ  
The applied 3d moment vector. 
- symbol
 -  Type:  Autodesk.Revit.DB.Structure LineLoadType  
The symbol of the LineLoad. Set a null reference ( Nothing in Visual Basic) to use default type. 
Return Value
If successful, returns the newly created LineLoad, a null reference ( Nothing in Visual Basic) otherwise.Exceptions
| Exception | Condition | 
|---|---|
| Autodesk.Revit.Exceptions ArgumentException | The element host was not found in the given document. | 
| Autodesk.Revit.Exceptions ArgumentNullException | A non-optional argument was NULL | 
| Autodesk.Revit.Exceptions ArgumentsInconsistentException | Thrown when all force and moment vectors are equal zero. | 
| Autodesk.Revit.Exceptions InvalidOperationException | Thrown if type could not be set for newly created line load. |
