I created a blend shape in Illustrator (to reproduce, draw two lines, apply Basic stroke to them, Object > blend > make, then Object > blend > expand).
I exported the image to SVG. I opened it in Inkscape.
When trying to plot it I get:
Warning: unable to plot <switch> object
found in file. Please convert it to a path first.
Elapsed time: 00:00 (minutes, seconds)
Length of path drawn: 0.00 m.
Total distance moved: 0.00 m.
But the file should consist of only lines…
