Pset_Tolerance Properties expressing the tolerance relating to locating and shaping of an intended element or feature. Range diameters are non-negative describing a linear, rectangular or boxed region . IfcProduct IfcTypeProduct IfcProduct,IfcTypeProduct ToleranceDescription General description of the tolerance associated to the element or feature, its source and implications.
