I converted a drawing in PDF format to DXF by using Aide PDF to DXF converter. The file was converted but as I open the output in AutoCAD I get a following error:

DXF read error on line 2275.
Invalid or incomplete DXF input -- drawing discarded.
Press ENTER to continue:

I have used Aide output in Autocad before and there were no errors for those files. It gives the mentioned error for only few drawings which I recently wanted to use in my Layout. Any help would be great.

Thanks.

Best regards,
Saad
