BeltMeasurement Property

On a curved surface, BeltMeasurement specifies where the grid's distances are measured.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 2015.0.0.0 (2015.0.0.0)

Syntax

C# 
public double BeltMeasurement { get; set; }
Visual Basic 
Public Property BeltMeasurement As Double
	Get
	Set
Visual C++ 
public:
property double BeltMeasurement {
	double get ();
	void set (double value);
}

Remarks

On a conical surface, the distance between the radial gridlines is not constant. To interpret the Distance property, a circumferential gridline is taken as the "belt." Distance is then measured along the belt. The BeltMeasurement property gives the location of the belt relative to the extremes of the surface. The belt is used whenever gridlines are not parallel. It defaults to 0.5.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentOutOfRangeException Thrown when beltMeasurement is outside the range [ 0.0, 1.0 ].
Autodesk.Revit.Exceptions InvalidOperationException Thrown when the gridlines are guaranteed to be parallel; check the HasBeltMeasurement property before using this property.
