Well, the Autodesk DXF format specification is quite wide - if a DXF file does not conform with that specification, it probably won't be readable for AutoCAD.]]> Thu, 17 Feb 2022 09:00:53 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=13677&PID=38157&title=opening-dxf#38157 <![CDATA[opening dxf : Thanks for your reply.

I have looked at file using notepade and it all looks similar to what you posted but no matter what cad I try it fails errors saying drawing not found and closes ]]> Tue, 15 Feb 2022 00:07:39 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=13677&PID=38154&title=opening-dxf#38154 <![CDATA[opening dxf : There are many DXF files which...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=13677&PID=38151&title=opening-dxf#38151 Author: Vladimir Michl

There are many DXF files which are not formatted properly. But a DXF file (text-based) should start with something like this:

  0
SECTION
  2
HEADER
  9
$ACADVER
  1
AC1009

and the "AC1009" (or similar) will match the AutoCAD version - see https://www.cadforum.cz/en/qaID.asp?tip=868

But any newer version of AutoCAD will open properly formatted DXF and DWG files from an older version.
