Errors loading dxf files on OpenSCAD - OS X

Hi Developers,

I really love your product. I use the OS X latest available files.

While trying to extrude a profile downloaded from the 8020 website, I get the errors listed below when I load the DXF file:

Compiling design (CSG Products generation)...
WARNING: Unsupported DXF Entity 'POINT' (2) in "../../OpenSCAD/libraries/DXF/25-2525.dxf".
WARNING: Unsupported DXF Entity 'ATTDEF' (11) in "../../OpenSCAD/libraries/DXF/25-2525.dxf".
Geometries in cache: 146

Is that something I should worry about?

Regards,

OpenSCAD is a bit picky about the .dxf files it supports.

Can you share the dxf you are trying to load?

Hi Basile,

Thanks for your reply. The file attached is one hat I downloaded from the 8020 website. I do not know how it was generated.

Other that the fact that it has a bit more rough edges on the curves I can
see nothing wrong.

After exporting it as svg from QCAD, importing it into Inkscape, ungrouping,
deleting the blue lines, merging all the paths as one, flattening beziers
with 0.1 and exporting again as dxf all I got better was a little better
curves. (That's apart the fact that the object generated from my dxf was not
centered and smaller than the original)

BTW Importing the original dxf I got the same 2 warnings.

Hi Basile,
Thank you for looking at it. I can live with the warning since the extrusion works fine.
I was just wondering if some parts of DXF were not processed by OpenSCAD.

When I have some spare time, I will look at the code doing the dxf import.

Best regards,

Currently a handcrafted importer is used
(https://github.com/openscad/openscad/blob/master/src/dxfdata.cc)
which does not support a number of entities found in DXF files.

The plan is to select an existing library and use that for import
and export of DXF files.
https://github.com/openscad/openscad/wiki/Project%3A-Improve-DXF-import-and-export

As far as I know, nobody is currently working on this, so ideas,
pointers to more libs to select from or any other help would be
very welcome :-).

ciao,
Torsten.
