I m using QGIS 2.18. I am getting the following error when I try to convert dxf to shapefile. The other software like online convertor and arcgis give no errors in converting the same shapefile. The program crashes.
If I don't care about any attributes attached to the features in the dxf, I simple load the dxf into QGis and use
save as to "convert" it into shape format. Otherwise there's CAD2Shape, a proprietary converter.
Worth to mention: Be sure your dxf has no z-values, otherwise QGis might not be able to work with the file properly.
