We've written a dxf export package for our electrical CAD product, however it seems that polylines render badly. To be geometrically accurate the polylines are widened by the linewidth, which gives accurate results in our package
When the dxf is imported into autocad we see this ...
and another DXF viewer (can't recall which) renders it slightly differently.
Why has the autocad render got an angled end on the left hand vertical side? (it's much more obvious with thicker lines).
One suggestion is we've drawn the polyline in our app with a circular brush.
Does our dxf file not include sufficient information? In autocad, _PEDIT and set a line width of 0 gives an accurate polyline (albeit with minimal line thickness).
I have a dxf you can look at too :-)
Thanks for looking
