Why am I unable to see certain line features in certain DWG or DXF files in ArcMap?
I've tried changing the symbology, converting the files (with Autodesk TrueView) to various iterations of the DWG standard and even getting a DXF.
In all cases, the lines do not show up in Arcmap at all. I can see the other layers in these DWG files, such as annotation and grid ticks. The most frustrating part is that the missing line is clearly visible in Autodesk.
Caveats: I'm not a trained CAD user. These files are being sent to me for review in GIS software by engineers using (presumably) CAD software.
Conditions: unknown DWG / DXF files. ArcMap 10.2.
Examples: A file that has been giving me this issue.
