If you have simplified the path please upload the file again.

Sure...
I am sorry, my brain is burnt...

FreeCAD_0.19-18403-Linux-Conda_Py3Qt5_glibc2.12-x86_64.AppImage also crashes...

if yes it is your svg generation on inkscape use normal svg and 96DPI What did you mean? Where are these settings? It is awful, terrible and horrible... :( Anybody, please, try a Sweep tool in my file: path3384 (or Sketch) and Sketch001. I simplified my path and it does not work again... :(((((((((...

I took your SVG. The Sweep tool works. But the result is wrong...
What Sketch did you use to form a shape for Sweep using?

You speak about a self-intersection in Path (Sketch). Am I right? I corrected it.
I asked about a self-intersection in a result geometry that is got after the Sweep tool.
I am sorry if I did not understand you...

Ok. Let's guess that Sweep worked out. It is ok.
What should I do with self-intersections after Sweep working?

no it is FreeCAD
i added the Cutter File
FC_cutter.jpg
FC_cuter.FCStd

Does Sweep have a wrong geometry?
It has some self-intersection.
Why does it work for you and it does not work for me?

the path has lots of intersection
jo can see it on the GREEN lines that are very tight at this intersections
need manuell tweeking

I did not understand how I can see them...

You missed the point. Selfintersection is not inside the sketch but in the resulting sweep geometry. This happens with tight internal arcs and long internal sections of the sweep profile. I reduce the bottom edge in Sketch001. FC crashes... I deleted sharp corners at feet and tried again. FC crashe...

See the selfintersection here: Check this thread for some explanation https://forum.freecadweb.org/viewtopic.php?f=3&t=39874 Thanks. I will study your link. I converted my contour to Sketch (with a tool of Draft) and deleted some self-intersection (they were!). Further, I tried to use Part Sweep wi...
