[HANUMAGOUDA]

Hi Group Members,
I am using CAM350-V7 to verify the Gerber. But now a days whenever i am trying to export the .dxf file from the Gerber, I could not able to open the .dxf file in Autocad. Because when ever i am creating the .dxf file, the file type will get change to "3dpcb DXF file". I am facing this problem past from 15 days, before it was working fine. Please find the attachment for you reference.
Kindly help me to come out of this problem.
Its very urgent, please help me ASAP.

Regards,
Hanumagouda Patil

What did you install or change 15 days ago then?

A 3D DXF program by chance?

In Autocad can you simply use file\file open and change the type to DXF then select and open the file?

Change your file associations to remove this association, then setup a new one for autocad.
