The position and orientation of the ReferencePoint.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 21.0.0.0 (21.1.1.109)

Syntax

C#
public void SetCoordinateSystem(
	Transform coordinateSystem
)
Visual Basic
Public Sub SetCoordinateSystem ( _
	coordinateSystem As Transform _
)
Visual C++
public:
void SetCoordinateSystem(
	Transform^ coordinateSystem
)

Parameters

coordinateSystem
Type: Autodesk.Revit.DB..::..Transform

Remarks

The position of the point is given by CoordinateSystem.Origin, and the orientation is specified by the three unit vectors CoordinateSystem.BasisX, BasisY, BasisZ. The basis vectors must be unit length and mutually perpendicular. Whenever the Reference property is not nullNothingnullptra null reference (Nothing in Visual Basic), changing the CoordinateSystem property has a compound effect. First the point is moved to the specified location. Then the point is moved to conform to its Reference, by the shortest possible distance.

Exceptions

ExceptionCondition
Autodesk.Revit.Exceptions..::..ArgumentException Thrown when coordinateSystem does not specify an orthonormal basis.
Autodesk.Revit.Exceptions..::..InvalidOperationException Thrown when CoordinateSystem is set while the Reference property is not nullNothingnullptra null reference (Nothing in Visual Basic), and the ReferencePoint is unable to move to the new location.
