I've received AutoCAD data for multiple projects. Usually I can add the data and begin creating GIS features. However, recently when I add the data, the files (point, polyline, etc...) are importing with empty attribute tables. My AutoCAD software knowledge is very limited. But when I open the dwg or dxf files in the software, all the linework displays correctly. Any suggestions on how make the linework visible in AutoCAD display in ArcMap?
