Out of Memory converting SVG

[insp]

Hello.
I have a problem converting SVG to Draft using "Convert bidirectionally between draft objects and Sketches".
Freecad eats up to 38G of memory and get killed by kernel

There are several improvements concerning SVGs in 0.19.

I think the flower is far too complex. You may tell us more about the big picture, what do you want to achieve in the end. You may get better help then.

any particular reason why you "have" to use the sketcher?
the svg loads just fine and is responsive in draft, and with draft/part wb you can probably do what you are looking for - just a different way and workflow compared to using the sketcher (including using a set of lines to make solids).

with that said, you are probably going to get further if you only do path by path to sketcher,
just doing the outer path is completing in a second (on a old subpar laptop), and has close to 800 dofs - just imagine how many dofs in total it would be for for all 600+ paths if you do it in one go.

The reason I have to use sketcher is that I want to generate Gcode.
convert svg to sketch, then "Create job", then "Engraving operation"

Actually this flower doesn't seem to be very complex I am really surprised freecad can't handle it.

800 degrees of Freedom sounds rather complex. It may not have many lines, but each of them is a not at all trivial B-spline.

You don't have to convert these to sketches, you can engrave the paths directly. I would strongly recommend to use the symmetry of the flower together with the PathArray operation.

Please, describe the workflow in a few words for engraving paths directly.
