In DXF a 3D polyline is a POLYLINE and so far what I'm getting is LWPOLYLINE with the DXF that I've generated. Source : http://docs.autodesk.com/ACD/2014/ENU/

This a sample of the dxf I've produced :

As you can see my output contains 3D points, but the format is somehow saying that this is 2D at a fixed z. I checked it is fixed at 328.5734, the z of the last point.

This is a DXF with the kind of object that I want :

EDIT 2 :

When I show attribute data for gloubiDrape my 3Dvector map, under browse data tab I get :

cat layer entity label
1 0 lwpolyline
2 0 lwpolyline

and under manage tables :

columnName dataType dataLength
cat integer 11
layer character 255
entity character 255
label character 255
