Problem with this dxf and openscad extrusion

Laszlo KREKACS
Dear List,

I have problem extruding this dxf file:
http://sites.google.com/site/laszlo123456789/1/tool_holder.dxf

Openscad source is only this:
linear_extrude(file = "tool_holder.dxf", layer = "nuts_access", height
= 40, convexity = 2);

Error message:
terminate called after throwing an instance of 'CGAL::Assertion_exception'
  what():  CGAL ERROR: assertion violation!
Expr: pe != 0
File: /usr/include/CGAL/Nef_3/polyhedron_3_to_nef_3.h
Line: 178
Terminated.

When the outline in the nuts_access layer was about two times bigger,
the program had no problem with it.

any ideas?

Im using yesterday's svn (r361).

Any ideas are welcome.

Best regards,
 Laszlo

The nuts_access layer of your file contains multiple circles and arcs  
with 0 radius.
One is located in thr origin and three more inside your outline.

We'll try to be more robust when handling such files. I've added this  
situation as a test case - hopefully we'll squish this one later today.

Keep reporting such issues and cheers,

Thank you for your quick answer!

Im a beginner in QCAD and maybe thats why I created accidentally some
0 radius circles...

I need to figure out how to check qcad sanity...

Best regards,
