Short description of error
Some files won't import completely. The importer crashes before finishing.

Exact steps for others to reproduce the error
Try to import this file: bug 2.7z. The original files gave 2 different errors, maybe the crash logs can help: error dxf 2.txt error dxf.txt

Your file has a spline with two point having the same location. The importer should actually handle this; for some reason it didn't.

2f3e4104de5a: convert.py line 178: it checked for the distance between two points, which would also allow to check for two points that are very close (replace the "0" with something very small). Now it also checks directly whether two points are the same.

@bliblu bli: be aware that you need to use the scale option if you import geometry that is that large or was generated in other units than meter. --> the unit scale option is available in the geo referencing panel. I had to use a scale of 0.001 to successfully import your file.

Thanks :) Fix works for the one error. Note that there is no such big object visible in the original file nor in the DXF when opened with our CAD program, it looks like one point was moved to 0,0,0. The original file being in Germany thus thousands of kilometers away from 0,0,0, it may be what makes the object so big.
I have an narrowed down file with the second error triggering a crash in our production file. bug 3.dxf.zip

@cnd would be good to add this fix to 2.78a :)

commit 1b58a90cd418 should solve your issues with bug 3.dxf.

Are you able to test it, so we can close this issue?

If you have an object that is far far away from 0,0,0 consider using the "Center geometry to scene" option. It's only available if your scene does not have a custom property "latitude" and "longitude" (a geo reference).
