Closed, InvalidPublic

Description

Blender Version
Broken: All
Worked: None

Short description of error
DXF_Exporter exports only polygon edges, don't exports besier curves
Exact steps for others to reproduce the error
This is test scene with def circle


It inclue working script from https://blender.stackexchange.com/questions/9305/export-bezier-curves
Looks like script exports true besier, but in three.js format i cannot to use it (i need universal dxf)
export js result
If i convert this quad to mesh, DXF_Exporter exported as poly lines
This is dxf made in Freecad, this is what i need for

It will be super if someone improve this musthave feature.

Thank you!

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

Think what you could do is:

  • have a look at https://cad4arch.com/dxf_exporter/ (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 https://blender.community/c/rightclickselect/], afraid we have to close this...
