|Summary||0001158: Import of 3D-dxf files failes|
|Description||Importing of dxf-files containing polygons in 3D freezes/crashes freecad. Import of the same files works just fine in heekscad which is supposed to be built on the same CAD-kernel.|
An example file is attached to this report.

||What is your FreeCAD version and OS? Under Windows with the latest development version and the 0.13.1828 I have no crash.|
I tested the DXF file with the latest HeeksCAD version. There it needs 13 sec to load the file while in FreeCAD we need only 4 sec.
There is a DXF importer for OpenCascade but this is not part of the open-source version. In FreeCAD we use a Python library and HeeksCAD must use a C++ library but I don't know if Dan Heeks has implemented or if it's a 3rd party library. I didn't find the source code in his SVN tree.
For me it also imports without any crash. And as far as I can tell the import is complete, no part is missing...
About the heeksCAD dxf importer, yes, I believe it was made by Dan Heeks from scratch. It was one of the best candidates I had to make a C++ importer for FreeCAD, because the code is very simple ( https://github.com/Heeks/heekscad/blob/master/src/HDxf.cpp ) so it's easier to maintain and most other dxf libs are old and not maintained anymore.
Anyway, fkluwe, can you check if any error message appears on the output or python windows?
I tried to open the file on the following system:
OS: Windows XP
Version: 0.14.2123 (Git)
Python version: 2.6.2
Qt version: 4.5.2
Coin version: 3.1.0
SoQt version: 1.4.1
OCC version: 6.5.1
FreeCad is thinking about the file for several minutes and then quits without any further comments. Maybe a memory issue? (3.4GB RAM)
||As freecad is quiting without any error messages it is difficult for me to provide any further information. Are there any log-files written by freecad which migh tbe helpful?|
||I've made a screenshot just before FreeCad silently quits, showing the excessive usage of memory by the program (attached file)|
Can you try opening another dxf file? Just to make sure the importer works at all...
Can you also start FreeCAD with logging enabled? For this, you must edit the desktop shortcut of FreeCAD, and change the executable name from "FreeCAD" to "FreeCAD -l". Then, run FreeCAD, and make it crash by opening the dxf file. After that you will have a log file (FreeCAD.log) in your FreeCAD user folder (I think C:/Docs and settings/your_user/Documents/FreeCAD but I'm not sure, you might have to search for a FreeCAD folder). Then upload the log file here, it might contain clues.
||Closing this because there is no more feedback|
