I have imported an IFC model from a steel fabricator (I believe they may use Tekla, as there are record formats in the file that are prefixed with Tekla). Each object or group of objects has a field "tag" under IfcElementAssembly record, although this record format is not present in the Resource Manager. I would like to find (select) objects or groups of objects in the model using the value in the "tag" field. I've tried to use Custom Selection... but this field does not seem to appear anywhere. Any ideas on how I would do such a selection in VW?
