Problems when importing dxf files created on other platforms

[Adam Sharpe]

Hi. I've had problems when importing dxfs created on other platforms (NanoCAD, AutoCAD) in that what were simple polylines are converted into polygons by the addition of a closing line between the end vertices. Has anyone else come across this issue and does anyone know how to resolve it?
