QCAD.org Forum

Hi,

We are adding SPLINE support for our DXF output-format for Gendl, our open-source KBE system (http://gendl.org).

I hope this is an appropriate place for this post. I'm trying to find some pointers for debugging what appears to be a subtle issue with a DXF file we are trying to output, containing a spline.

The attached DXF opens fine in QCad, but fails in Autodesk A360 viewer.

So apparently QCad is more forgiving than Autodesk A360 viewer. Is there a way in QCad to examine the DXF file for any "warnings" or malformed input, or can anyone see something obviously incorrect with this file? Removing the SPLINE entities results in it working in Autodesk 360 viewer -- so apparently there is something wrong in the SPLINE entities.

I've attached the text-format DXF file as well as a screen capture of how it looks when opened with QCad.

Best Regards,

Hi dcooper8,

I'm not the right guy to help you with any kind of coding but maybe my findings are helpful for your own analyse.

FAQ:
I can open your dxf in the Community Edition but QCAD Pro and A360 Viewer fails.
If I open your test file in CE - save it again - then I'm able to read it correct in Pro.
Working with QCAD CE - copying all entities from Layer 0 to a new one will make splines and text readable for the A360 Viewer.
Hope that helps.

Dear Husky,

Thank you very much for looking at it! I will certainly use your results in my analysis, and will report here what I find out!

Saving with QCad CE & trying to re-open was definitely a good idea, and something I should have tried myself... so now I can try doing a diff analysis on our original file vs the QCad CE saved version (the QCad version will have a lot of extra header and footer stuff, which I can try stripping down to the minimum working set).

Regards,

Dave
