https://forums.autodesk.com/t5/autocad-forum/fatal-error-unhandled-access-violation-reading-0xffffffff/m-p/6016356#M346148 <P>I believe I have the same case here.</P><P>Inserting rows to table causes fatal error. It does not happen immediately, but after repeating the operation for a few times the crash eventually happens.</P><P>After reopening the drawing I can insert&nbsp;a couple of rows again at desired place, but then again it crashes. This is the case with all my drawings and has been present at least since release 2014 (now I'm on 2016). I'm using Civil 3D.</P> Sun, 31 Jan 2016 19:48:43 GMT robert06 2016-01-31T19:48:43Z
