on QGIS master it gives error while exporting to shape, but it gives also a result (attached). Please try and report back. Cheers.

Export to vector file failed.

DXF can contain points, lines and polygons - this one comes from an AutoCAD user. (So can WKT, which I also tried to use for another user's maps earlier - see #7703.) QGIS needs to creat three layers for this DXF, one pont, one line, one polygon. It doesn't, and that's why it fails. This is not only a bug, but a blocker for bringing in these AutoCAD maps. I attach a PDF from the user showing what the result should look like, also a GIF of what I get in QGIS 1.8 with this file.

I tried to import the dxf file as it is, obtaining the same error. but, performing the following feature subset:
"SubClasses" = 'AcDbEntity:AcDbLine' OR "SubClasses" = 'AcDbEntity:AcDbPolyline' OR "SubClasses" = 'AcDbEntity:AcDbCircle' OR "SubClasses" = 'AcDbEntity:AcDbCircle:AcDbArc'
and then saving layer as shape, I obtained the polyline shape attached.
Performing a feature subset:
"SubClasses" = 'AcDbEntity:AcDbText'
In order to isolate the only text features, I was able to correctly represent text in QGIS, but when I tried to export the layer as shape, I was prompted by: |Export to vector file failed. |Error: Feature write errors
reported in your previous messages. It seems that QGIS tries to import text layer in a line shape: |Feature creation error (OGR error: Attempt to write non-linestring (POINT) geometry to ARC type |shapefile.)
regardless of text layer feature type (point, see the project attached); this can be the problem.
BTW, I can't open the dwg file in autocat (autocad LT 2009), so check the Autocad version, It could be an unsupported one.
Please, give a feedback so that we can refine the problem

I've asked the user for his version. In the meantime, here is the native DWG of AutoCAD.
The drawing was originally in Drafix CAD - it was bought by AutoCAD and shut down; the user migrated to AutoCAD Lt 2008 which is what has produced his DWG and DXF.

I exported the DWG to dxf2000 version. I exported then to shp without problem (see attached shape).
The problem was surely related to dxf version. Used QGIS current master, but it works the same with 1.8

In order to correctly export dxf layer to shape, I suggest to follow these steps:

1. open dxf in QGIS;
2. make a feature subset depending on type of feature you are interested (then, you have to reset the symbology type (point, line, area), maybe it could not be the right one);
3. Save as the layer

I think that you can close this ticket.

Hi jhon, the user manual does not contain anything about this because this is a workaround that I use for representing CAD drawing in QGIS. I found this way through some attemps. I attached a QGIS project, you have only to reconnect the dxf you find to the project. See how I have represented the different layers (based from different subclesses of the same dxf file).
