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?

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 use Inkscape 0.91.

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

The crash happens on the first sharp right bend if going from the section to the left. My guess is, that the path segments are very slightly non tangential and that this causes problems. Have you tried converting the path into a sketch?

Did you mean a selected segment of the path (path3384 or Sketch) on an attached screenshot?

Yes, I have. It is "Sketch" in my file. I used it with a Sweep tool. I had a same result...

this kind of work is not on FreeCAD

thats why we got multiple systems for CAD/Nurb/svg/png/dxf

I will be very glad for your manual, thanks :)
It seems, it will need to study Blender or something like one...
I wanted to use only FC, but I already use Inkscape :lol:

the importent one is gimp
to offset the shape
in inkscape
you need to tweaken also the settings on Bitmap Vectorising
there are options on the Reiter
as pixel limits from 2->4
the shape precision to be svg from 0,6 to 1or even 1,2
there is another option that gives you the toleranz from 0,2 set it to 0,6

i guss you already did get the selection on png load to get smooth corners

there is lots to do bevor Fc or Blender that makes live very easy
