impossible to open / import DXF in linux

[Chris]

Hi' I've just installed the latest Ubuntu 9.04 final on my computer. I've juste compiled the latest Inkscape 0.46+devel r21213.

I just tried to import a DXF file and had 2 issues. In a first time there was a problem that I tried to fix with this command line :

sudo make install |grep dxf

here's what I got : (I'm french)

 /usr/bin/install -c 'dxf_input.py' '/usr/local/share/inkscape/extensions/dxf_input.py'
 /usr/bin/install -c 'dxf_outlines.py' '/usr/local/share/inkscape/extensions/dxf_outlines.py'
 /usr/bin/install -c 'dxf_templates.py' '/usr/local/share/inkscape/extensions/dxf_templates.py'
 /usr/bin/install -c 'ps2dxf.sh' '/usr/local/share/inkscape/extensions/ps2dxf.sh'
 /usr/bin/install -c -m 644 'dxf_input.inx' '/usr/local/share/inkscape/extensions/dxf_input.inx'
 /usr/bin/install -c -m 644 'dxf_outlines.inx' '/usr/local/share/inkscape/extensions/dxf_outlines.inx'
 /usr/bin/install -c -m 644 'dxf_output.inx' '/usr/local/share/inkscape/extensions/dxf_output.inx'

/usr/bin/install: ne peut évaluer `./dz.gmo': Aucun fichier ou dossier de ce type
/usr/bin/install: ne peut évaluer `./zh_TW.gmo': Aucun fichier ou dossier de ce type

And lastly here's the error reported by Inkscape :

Traceback (most recent call last):
  File "/usr/local/share/inkscape/extensions/dxf_input.py", line 348, in <module>
    desc.text = '%s - scale = %f' % (args[0], scale)

  File "apihelpers.pxi", line 1136, in lxml.etree._utf8 (src/lxml/lxml.etree.c:36998)
ValueError: All strings must be XML compatible: Unicode or ASCII, no NULL bytes

I hope this is not an already bug reported I've not found any thing on this

Greatings,

could you attach the .dxf file you are trying to import?

[Alvin Penner (apenner)]

  Attached is a modified version of the file dxf_input.py which should fix the problem. Could you tell me if this works?
  This has been committed to rev 21227

Hi' I replaced the dxf_input.py by the one in the link you sent. I tried again to open the same file that caused the same error BUT the file was stored on an USB key so I copied it on the desktop to ensure that the bug couldn't come from the "location" or "device" and surprisingly inkscape was able to open it. As I launched Inkscape from a terminal here's what it "says" :

** (inkscape:7017): WARNING **: Malformed URI

I can't say now that I replaced the dxf_input.py file if it is because of the new one that it work or if the trick is that it doesn't want to load from a USB key...

I'll send you the dfx file I was trying to work with. Perhaps it should help to determine the problem.

Thx for being so reactive and for this great program !!!

- there are three separate issues that have shown up here:
- the original problem was that there were non-Ascii characters in the filename, either the name itself, or perhaps the directory name. Perhaps the USB drive had a folder name with characters such as è or é in it. This has been fixed (I believe) in the patch I submitted yesterday.
- the second problem was the messages about Malformed URI. I got these messages as well, but ignored them since they are not generated by the script that is importing .dxf, this is a separate issue from .dxf.
- the third issue is the presence of Blocks in the .dxf file. The support for Blocks is somewhat limited in the Python script. I loaded the original .dxf file into Inkscape but the quality of the rendering was poor. So I loaded the .dxf file into QCad and used the menu procedure Block | Explode. I then re-loaded the new .dxf file into Inkscape and got a better result, attached below.

    If the procedure to explode Blocks is available in your CAD program, then I would recommend using it before you try to import the dxf file into Inkscape. This may mean exporting a separate output .dxf file just for Inkscape.
