I am sending Solidworks .dxf converted files to a customer for nesting in their Sigmanest software for laser cutting.  Sigmanest is showing all arcs as double lines, one arc on top of the other.  Currently, the customer is manually removing each arc.  Is this a Solidworks issue, or a Sigmanest issue?  If it is Solidworks, how can I eliminate the problem?

Thanks,

Richard
