For some time now, I can't open a text saved in DXF or DWG to generate a 3D text.
I get the message " DXF file without HEADER description. Some data cannot be imported " which appears and nothing is displayed... 
I recently changed my Post and some settings, or options, must have been omitted but I can't remember where, and how, to adjust these settings to make it work again.
Can anyone help me?
Thank you in advance!
Hello and welcome Frederic_RICHARD,
I'm not a Catia user, only V5, but I'm not a very big user.
I found a video=>https://www.youtube.com/watch?v=Id-40z0s7Cg
and this one in English but it does =>https://www.youtube.com/watch?v=l0YX-YSoCYQ
Or maybe a simple copy/paste.
Maybe it can help.
Good luck, @+.
