Parameters
- document
- Type: Autodesk.Revit.DBDocument
 The document in which the new BeamSystem is created.
- profile
- Type: System.Collections.GenericIListCurve
 The profile of the BeamSystem.
- level
- Type: Autodesk.Revit.DBLevel
 The level on which the BeamSystem is to be created. The work-plane of the BeamSystem will be the sketch plane associated with the Level. If there is no current sketch plane associated with the level yet, we will create a default one.
- direction
- Type: Autodesk.Revit.DBXYZ
 The direction is the direction of the BeamSystem.
- is3d
- Type: SystemBoolean
 Whether the BeamSystem is 3D. If the BeamSystem is 3D, the sketchPlane must be a level, otherwise an exception will be thrown.
Return Value
If successful, a new BeamSystem object will be returned.Exceptions
