DXF Spline To Polyline

DXF Spline To Polyline

System operacyjny:


Autodesk® Fusion 360™ add-in lets the user export the currently active sketch to a DXF file in which the splines have been converted to polylines.


Some laser cutters do not work with splines. In order to avoid having to open the DXF in another product to do the conversion, this add-in does that for you.

  • Does not appear after installation
    Fhr Phoenix | maja 09, 2024 Sprawdzone pobranie (Co to jest?)

    Title says it all, it does not appear in Fusion, no matter what (selecting the sketch, editing it, not selecting it, or whatever)

  • It worked the first time I used it now it does not actually convert the splines. Weird.
    William Donnelly | listopada 24, 2023 Sprawdzone pobranie (Co to jest?)

    Idk what happened but I am pressing the same button and it is now exporting as if it never converted them. With some artifacts even.

  • Works perfect for me
    Aleyna Ekinci | października 17, 2023 Sprawdzone pobranie (Co to jest?)

    Now I don't have to try to convert splines into polies. Wish Autocad has this tool in it.


  • Did not export the curve
    Cedric Van Laere | sierpnia 12, 2023 Sprawdzone pobranie (Co to jest?)

    Sadly does not work and works worse for me as it also does not export another curve that the normal "save to dxf" did export correcly.

  • Does not work in 2020 Fusion...
    Karstein Kvistad | sierpnia 30, 2022 Sprawdzone pobranie (Co to jest?)

    This does not work at all. The program does not appear after installing on Mac M1

    Jumpei Arashi | października 15, 2022

    same here. In Inkspace still some spline can not be loaded.

    Josh Silverstone | grudnia 05, 2022

    Edit the sketch in F360, open the Create pull-down (for some reason), it's at the bottom and will export directly from there.

    Stef Lak | marca 17, 2023

    horrible, the plugin is there, but the export is totally unusable, no curves, straight lines, shaggy. Any idea how to export it to cut on laser? Thx.

  • Works great!!!
    Miguel PLazas | kwietnia 07, 2022 Sprawdzone pobranie (Co to jest?)

    Why is this not a default option...

  • very helpful
    Ianbelinchon Ianbelinchon | czerwca 03, 2021 Sprawdzone pobranie (Co to jest?)

    Does exactly what i needed. Creating files to laser-cut. My laser works best when using CDraw, so this helps to not have to redraw the splines in there. Perfect!

  • Can we get to convert splines without saving to dxf?
    Lee Thompson | sierpnia 02, 2020 Sprawdzone pobranie (Co to jest?)

    I dont need to export to a dfx, but sometimes it would be nice to just convert splines.


    I can save as dfx and then import that saved file, but that seems a bit silly

    Please ask on the Fusion 360 Forum if people have any suggestion for that: https://forums.autodesk.com/t5/fusion-360/ct-p/1234

  • Works perfectly!
    Ben Krasnow | października 14, 2019 Sprawdzone pobranie (Co to jest?)

    I'm making circuit board outlines in F360, and exporting to KiCad and my laser cutter for protyping the fitment. Having splines in the outline causes the import process to fail, or to import with very strange errors.  Using this plugin solves the problem perfectly.

  • Amazing for KiCad
    Alberto Ramirez | września 13, 2019 Sprawdzone pobranie (Co to jest?)

    Wanted to use a DXF file in KiCad but quickly found out that it doesn't support splines. Searched online on how to import a DXF file with splines but many solutions required to download programs. This quickly makes the file I need. Great job

  • Really nice tool, made some changes to get it to work with the new preview UI
    Alex Lenting | stycznia 29, 2019 Sprawdzone pobranie (Co to jest?)

    Nice tool, to get it to work in the new preview UI you have to change the python code a bit.

    line 8 I changed to:

    panelToUse = 'SolidModifyPanel'

    added this line on 240:

    toolbarControlsPanel_ = toolbarPanel_.controls

    Adam Nagy (Wydawca) | stycznia 30, 2019

    Thanks for the tip for those who want to keep the command in the Model environment. Otherwise it will just show up in the Sketch environment's Create panel.

  • Very useful, Does not as of 2019-01-18 work with UI preview
    Tuomas Lukka | stycznia 18, 2019

    This is so useful that it should really be part of fusion 360 proper

    Adam Nagy (Wydawca) | stycznia 30, 2019

    It does now. It just shows up in the Sketch environment's Create panel. You have to double-click a sketch in order to get into the Sketch environment (where the Sketch tab will show up)

  • Great, only missing arc corners
    Wietse Van Geel | września 22, 2018 Sprawdzone pobranie (Co to jest?)

    This addon saves me a lot of time redrawing splines. But for me one thing is missing: arcs are made into polylines with a amount of segments depending on the chosen amount of segments.

    It would be great if the addon recognizes arc segments in the spline and converts them to arcs (fillet) in the .dxf. Now I'm doing this manual using r=sqrt((c^2)/(2*(1-cos(180-A))) where r is the radius of the desired fillet, c is the distance between the two points connecting the arc to the lines, and A is the angle between the two lines to which the arc is connected.

  • Fantastic - A Critical Missing Feature in Fusion
    Kenneth Maclean | sierpnia 14, 2018 Sprawdzone pobranie (Co to jest?)

    Works like a charm, and is exactly what I needed when sending parts out for external fab.

    It is unfortunate that this has to exist as an add-in though. It should be a default option during the export process in Fusion 360. Not being able to handle splinese is an extremely common problem when dealing with older laser cutters, waterjet cutters or other 2D CNC machines.

  • KiCad loves it

  • Saved me on this one
    Varnell465 Varnell465 | stycznia 25, 2018 Sprawdzone pobranie (Co to jest?)

    Work like a charm. Fusion has limited export file extensions and the program I run to generate CNC Router toolpaths will import dxf format. Wish Fusion 360 exported dxf directly with the add-in but this works well.

  • Thank you
    Evann Dalton | stycznia 20, 2018 Sprawdzone pobranie (Co to jest?)

    Thank you for updating this recently I used to use this and then I ran into the issue where it would not activate the sketch I then cried and gave my puppy a dirty look. No more though!!

  • Nope -> Yup!
    Mark Honeth | maja 05, 2017 Sprawdzone pobranie (Co to jest?)

    Had issues exporting sketch splines to DXF the default way, went to the forums, got referred here, tried it and the results are even worse. Ended up just patching the missing splines back into the DXF using Inkscape. Edit: There must have been something weird with the certain version of Fusion I was using because since updating the app works fine. It's the perfect workaround for the default "Save as DXF" which gives really weird results.

    Adam Nagy (Wydawca) | maja 08, 2017

    Though the main purpose of these apps from my team is to showcase the power of the API and everyone is welcome to use the source code and modify it as they wish, I'd still be interested in seeing the model it fails to work with. Would you mind contacting us on fusion.apps@autodesk.com to provide more information? Thank you!

  • Excellent App
    Sascha Hirschhausen-Funk | kwietnia 27, 2017 Sprawdzone pobranie (Co to jest?)

    Now I can prepare my sketches for the lasercutter. Thank you!

  • Excellent
    Desire Nwaobasi | kwietnia 05, 2017 Sprawdzone pobranie (Co to jest?)

    This should be merged by default in the main app.

  • Works like a charm, allows me to export DXF files of spline entities, which I couldn't do with previous versions of F360
    Justin Pither | listopada 30, 2016 Sprawdzone pobranie (Co to jest?)

    This does exactly what it says on the tin. A little fiddly to get started with, but it is now indispensable to me - I use it multiple times per day.
