problems dxf and laser cutting

[Oxcart12]

Bye to all,
I'm finding a problem with laser cutting in the company.
when I supply the dxf file exported from its table, the cutting software does not manage the spline for which it does not display them.
Did any of you have a similar problem? How did you solve it?
is there a set that allows export as a poly line or as a series of arches and lines?

Thank you very much

search options for settings for the dxf format.

What version do you use?

normally cnc machines do not recognize spline. the solutions are two:
- Usually cads have in export options how to replace spline
- cncs can have in pre-processor the set of recognition
- if not possible the two options must be made by hand a series of curves or knowing the laws of equations you can speed up

in fact my request was to avoid hand reconstruction

with catia you have to export to dxf version r12 and then recall the dxf and explode the spline
spline becomes an object of small lines

how do you explode the spline?

Select the spline of your dxf, right click explode.
but you can only do it on the exported dxf in the r12 version
after that.. save still in dxf and pass it to your cnc

Thank you so much, you're always a myth!
