Filetype to export curves for FEA?

I need to export a set of curves to be run through Finite Element Analysis.
(and I do not know which software will be used for the FEA).

I previously exported a DXF, but resulted in a mess of unusable lines :frowning:


Any advice?
Which filetype / settings are recommended to export curves for FEA?

Hello- can you post an example of the curves you would like to export? That output for dxf seems un-expected…


A set of curves in 3D. (a voronoi structure)

Something like this:

Hello - the idea is to test the export process - I need the curves that you are exporting. If you cannot post an example here, please sent to and please include a link back to this topic in your comments.


attached a sample fo the curve type.

curves_FEA.3dm (3.6 MB)

Hello - does this file work OK?

vornoi.dxf (415.1 KB)


:+1: it seems ok to me.

is DXF the standard filetype for FEA with curves?

Hello- I do not know the answer to that question, but, how did you get the messy results from your test. is more what I’d like to know.


I just realised that I exported without joining first. :man_facepalming:
