The exporter included in blender has no official support for beziers.

Think what you could do is:

  • have a look at (there is another version of the exporter that has support for this), this is from the same author that maintains the version officially supported in blender
  • you could export (nurbs) curves to OBJ instead [with the Write Nurbs option], not sure if this can be imported correctly in Freecad (or wherever you need it)?
  • (not recommended, speculative, if you're a coder: check the DXF exporter in blender, there is code for curves [but commented in many places] -- I havent tried this, this could possibly be made working by uncommenting... it is GPL after all...)

That all being said, this is not officially supported and looks more like a feature request [which is better suited at places like], afraid we have to close this...
