I imported an AutoCAD 2000 drawing (audited and purged) containing nothing but polylines into ArcMap 10. I tried to export to a shapefile using Conversion Tools=> to Shapefile=> Feature Class to Shapefile (Multiple) tool. It worked fine, except a few polylines were inexplicably left out. I figured it was because they weren't closed, so I went into the CAD file, redrew those objects, and made sure they were closed.
When I tried to convert the CAD file to a shapefile again, I kept getting the following error:
"Failed to convert: Parcels.dwg Group Layer\Parcels.dwg Polyline Problem generating Output Name (Error 999999: error executing function)"
I am mystified as to why redrawing less than a half dozen polyline shapes in the CAD drawing somehow screwed everything up. Does anyone have any idea what happened, and more importantly: how can I successfully convert this CAD file to a polygon shapefile?
