Hello everyone I can't see any possibility to add string descriptor to my network dataset. As it seams, only numeric types of descriptor are available. What I want to do is create a parameterized restriction using road identificator (which is of string type) as input parameter to avoid specified road in tracing. The restriction evaluator script should be something like: Dim restrict,param restrict = False param = ParameterValueByName("roadIdStringParam") If (Edge.AttributeValueByName( "roadIdStringDescriptor" ) = param) Then restrict = True End If of course, it doesn't work because roadIdStringDescriptor cannot be defined as string. Does anybody have any suggestion for a workaround? Or am I getting it all wrong? I am using ArcGis 10.1. Thanks in advance Daniel
