jeroend Posted February 15, 2012 Share Posted February 15, 2012 I'm building my website / application where users can upload and/or customize existing drawings to fit their own needs. It all worked with SVG, but now I'm working on a DXF export, so I can send drawings to cnc routers. I do have one program (viacad) which is showing my dxf drawings, however I send a few of my drawings to a cnc / carpenter shop who could not read my generated (attached boomerang.dxf) file with autocad 2010 ( internal error: !dbr12dxfin.cpp@2318 ) after which autocad is trying to send a report to autodesk. I'd really appreciate if somebody could give me hints on what's wrong. You can experiment yourself with my online dxf generation DXF (You need a modern non IE browser, firefox v10 or chrome v16 are just fine) boomerang.dxf Quote Link to comment Share on other sites More sharing options...
Tiger Posted February 15, 2012 Share Posted February 15, 2012 Gave the same error in AutoCAD 2012, and then AutoCAD crashed. Quote Link to comment Share on other sites More sharing options...
jeroend Posted February 15, 2012 Author Share Posted February 15, 2012 Hmm I'm sorry about that . Future readers be warned. Using viacad I did re-export my drawing, now its four times as big as the original dxf file and the polyline has gone, but maybe it won't crash autocad anymore. boomerang_via.dxf Quote Link to comment Share on other sites More sharing options...
Tiger Posted February 15, 2012 Share Posted February 15, 2012 Couldn't open that either, got this on the commandline - and a window before that, picture in a second. Improper table entry name PUNCH!_SOFTWARE_VIACAD on line 1288. Invalid or incomplete DXF input -- drawing discarded. Quote Link to comment Share on other sites More sharing options...
Tiger Posted February 15, 2012 Share Posted February 15, 2012 Reading on Viacads homepage, they claim that they can export and import to DXF -perhaps this is something they can help you with? Quote Link to comment Share on other sites More sharing options...
jeroend Posted February 15, 2012 Author Share Posted February 15, 2012 Thanks for your replies and testing so far. I'm not to happy with ViaCad and they have not been very responsive to issues in the past. It's too bad that they don't produce proper dxf, but its a very cheap product. I'd be more happy if i could solve my generation issues, or get a clear explanation what is going wrong in my little file. Autocad is unfortunately not very informative about the reason of the crash, and it's hard to find any reference material. Quote Link to comment Share on other sites More sharing options...
Tiger Posted February 15, 2012 Share Posted February 15, 2012 Sorry I can't be of more help If all you are looking for is 2D there are a number of cheaper (everything is cheaper than autocad...) alternatives that get recommended on this forum on a regular basis, search for 'autocad clone' if you are interested.

jeroend Posted February 15, 2012 Author Share Posted February 15, 2012 I think that my target should be Autocad, (you can't get fired if you deliver autocad compatible files right?) I went back to the original python package (dxfwrite), from which I basically borrowed the logic. DXFwrite is supposed to generate R12 DXF. Attached 2 files which come directly from dxfwrite. Again a quick test is appreciated (beware that my previous tests happened to crash autocad ) lines_layer.dxf lines.dxf Quote Link to comment Share on other sites More sharing options...
Tiger Posted February 16, 2012 Share Posted February 16, 2012 Both files opened without a hitch Quote Link to comment Share on other sites More sharing options...
