Hello again.
Ok, so I can duplicate the error. I tried both the 100cerca and the camino tables in PostGIS (imported from shapefiles). When I open them as OgrLayers in MapWinGIS, I get a ShapeType of SHP_NULLSHAPE. So next I will have to debug into the code to determine if the breakdown is in GDAL or in MapWinGIS.
I’ll let you know what I find.
My feeling is that it is not a problem with 3D, but with the MultiLineString type. Are the geometies acually multipart-linestrings, or are they all actually single-part polylines? Could they be converted to single-part polylines?
Regards.
EDIT: I also tried importing with the Option “Generate simple geometries instead of MULTI geometries” and the problem still exists.
