Exceptions

Exception	Condition
ArgumentOutOfRangeException	When setting this property: The value normalTolerance is outside the allowable range of values for NormalTolerance tessellation parameter.
InvalidOperationException	NormalTolerance tessellation parameter is default (hasn't been explicitly set by the user) and cannot be obtained now.

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 (10.0 degrees), Medium (15.0 degrees) and Coarse (30.0 degrees) 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.
