I'm trying to export a series of shapefiles to CAD. I've completed this exercise successfully in the past, but I'm trying unsuccessfully. I've tried both polyline and polygon files containing about 20,000 features. If I reduce the number to 100 - 1000 the conversion is successful. Starting the conversion typically results in an failure around minute 3. Attempted conversion to DXF as opposed to DWG results in an empty file. Any thoughts or recommendations would be welcome.

Thanks,

Kim
