SurfaceTolerance Property

The maximum distance between mesh triangles and model geometry. This is a percentage value. By exporting, the real value of surface tolerance is calculated as a percent from the length of the diameter of the body bounding box. The minimum allowed value is 0.001%. The maximum allowed value is 1.0%. Default value is 0.1%.

Syntax

C#
public double SurfaceTolerance { get; set; }

Visual C++
public:
property double SurfaceTolerance {
	double get ();
	void set (double value);
}

Remarks

This property can be set by using export resolution type (by creation of OBJExportOptions or using [!:Autodesk::Revit::DB::OBJExportOptions::setTessellationSettings(ExportResolution::Enum)] method). In the case of Fine (0.005%), Medium (0.016%) and Coarse (0.04%) resolutions, this property is considered as explicitly set by the user. In the case of Custom resolution type, this property is only allowed to be obtained if it has been explicitly set.

Exceptions

ExceptionCondition
Autodesk.Revit.ExceptionsArgumentOutOfRangeException When setting this property: The value surfaceTolerance is outside the allowable range of values for SurfaceTolerance tessellation parameter.
Autodesk.Revit.ExceptionsInvalidOperationException SurfaceTolerance tessellation parameter is default (hasn't been explicitly set by the user) and cannot be obtained now.
