Bug report - problems in dxf export

[jcf]

Hi,
I just experienced another bug in the DXF export that occurs in both versions 0.16 and 0.17, with a slightly different behaviour.

My (test) drawing is a very simple 2D drawing found here:
staff.ltam.lu/feljc/software/cnc/testdrawing.fcstd
consisting of 2 rectangles, 5 circles, 1 polygon and 1 line.

I tried to export it and import it to HeeksCAD, and it was wrong.
The fault was not on Heeks, as, when I tried to re-import the DXF to FreeCAd, it showed the same behaviour as in HeeksCAD.

The strange thing is that for example from the 5 circles, 2 are missing (however the keyword CIRCLE is to be found 5 times in the DXF file).

Any idea to this?

Or is there a better file format to use for this exchange ( FreeCAD to Heeks) ?

I tried to import the DXF file to Inkscape, and this was not succesful either:

"4 ENTITIES of type POLYLINE encountered and ignored. Please try to convert to Release 13 format using QCad."

There seems to be a file format error.

I found out something

(in freecad daily 0.17, OS: Linux Mint 17.3 Rosa
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.10950 (Git)
Build type: None
Branch: master
Hash: 6368b2f822cf838ee6c50ebf62480ff86c214317

:

it has to do with export preferences.
If I check "Project exported objects along current view direction" in the DXF export options, my test file is imported correctly into FreeCAd, and also into HeeksCAD. Good to know!
