Hi, 

I have been having some issues with exporting dxf files from Rhino 5.0. 

Curves, splines and arcs are been simplify to straight lines depending on the settings (tolerance and angle).

At the moment Im checking all exported file one by one. And changin the settings to specific tolerance and angle of the curves...

The thing is that in Rhino 4.0 I did not had this issue ( see att for the setting  I use to used in Rhino 4).

If someone have any ideas of how solve this isseu that would be great..

thnx.
