CAD to GIS – Export Contour Lines from CAD to QGIS

Question

I've been using GIS softwares in the past few years by I'm new using AutoCAD.

Well, I have contour lines in AutoCAD and I want to export it into QGIS (I also have access to ArcMAP).

I saved as .dxf (AutoCAD 2007/LT 2007 DXF) in AutoCAD. It opened fine in QGIS. However, it seems that didn't export the contour values (Take a look in the attribute table).

Am I missing some step?

Answer 1

If it is 3D DXF, follow the steps:

1. import the dxf in QGIS (DRAG & DROP or CTRL + V);
2. save as vectors (as the right mouse button);
3. add new field Z (integer);
4. Browser Panel to create a new database spatialite;
5. DBManager to import the shape in the newly created database;
6. run the update query;

step 1

step 2

step 3 - add new field Z

step 5 -DB Manager

step 6 - query
