Pretty looking QGIS contour lines with Z coordinate exported to Autocad DXF
The major challenge when exporting data from QGIS to Autocad DXF is to make sure we export all tree dimensions coordinates XYZ because using default contour vectors producing tools in QGIS we usually only get X and Y coordinates with elevation value saved in Attributes Table that doesn't get exported in DXF file to be used in Autocad. In this article we explain how to export in Autocad DXF format the contour lines processed in QGIS.
