Importing a shapefile fails with the error message 'This shapefile type is not supported'.
PTV Visum does not support following data types for polylines: - '(15)' stands for 'POLYGONZ', which are polygons with Z-coordinates. These are not supported because polygons in Visum do not have any Z-coordinate. Workaround: When saving the shapefile in ArcGIS (or another software) select another data type - POLYGON or POLYLINE. Since PTV Visum 11.50-02 PolygonM und PolygonZ are supported, but the Z-coordinates are omitted. - '(8)' stands for MultiPoint and is still not supported. Workaround: Use Point instead.
