Create Method (Document, IList(Curve), Level, Int32, Boolean)

Beam System Create(Document, IList Curve , Level, Int 32, Boolean) Method

Creates a new BeamSystem with specified profile curves.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static BeamSystem Create(
	Document document,
	IList<Curve> profile,
	Level level,
	int curveIndexForDirection,
	bool is3d
)

Parameters

document Document
The document in which the new BeamSystem is created.
profile IList Curve
The profile of the BeamSystem.
level Level
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.
curveIndexForDirection Int32
Index of the curve in the profile to be used as direction. '0' means the direction to use the first curve in profile. The curve from the profile to be used as direction must be a Line.
is3d Boolean
Whether the BeamSystem is 3D. If the BeamSystem is 3D, the sketchPlane must be a level, otherwise an exception will be thrown.

Return Value

BeamSystem
If successful, a new BeamSystem object will be returned.
Exceptions
Exception Condition
ArgumentException The input profile contains at least one helical curve and is not supported for this operation. -or- The curve index must be valid and the curve to be used as direction must be a Line. -or- The input level does not have associated plan view. -or- The plan view associated with the input level is not valid. -or- Can not get valid sketch plane from the input level.
ArgumentNullException A non-optional argument was null
ModificationForbiddenException The document is in failure mode: an operation has failed, and Revit requires the user to either cancel the operation or fix the problem (usually by deleting certain elements). -or- The document is being loaded, or is in the midst of another sensitive process.
ModificationOutsideTransactionException The document has no open transaction.
Example 
// Build a profile for the beam system creation
XYZ first = new XYZ(0, 0, 0);
XYZ second = new XYZ(40, 0, 0);
XYZ third = new XYZ(40, 25, 0);
XYZ fourth = new XYZ(0, 25, 0);
List<Curve> profile = new List<Curve>();
profile.Add(Line.CreateBound(first, second));
profile.Add(Line.CreateBound(second, third));
profile.Add(Line.CreateBound(third, fourth));
profile.Add(Line.CreateBound(fourth, first));

// Create a beam system
BeamSystem beamSystem = BeamSystem.Create(document, profile, level, 0, false);
if (null != beamSystem)
{
    // Change some properties, such as elevation
    Parameter elevationPara = beamSystem.get_Parameter(BuiltInParameter.INSTANCE_ELEVATION_PARAM);
    if (null != elevationPara)
    {
        elevationPara.Set(10.0);
    }
}
