Today I found an error in one of our exported DXF files,
A couple of circles were exported with a larger radius and incorrect position.
the rhino file with isolated curves:
Hi Willem - thanks for the report and details, I’ll check it.
@Willem - one thing I see is that the circles are not true circles in Rhino - not that it should mess them up on export but still, might be something to check - the curves might not be what you expect? They do not simplify (SimplifyCrv) to circles either.
I see the problem you report with 72007 Natural - and even with out the simplify arcs etc a re-import, apart from the circles is not very close to the original in places-
