Turning a shape into a line

Inkscape is capable of doing what I was looking for but it doesn’t completely solve my problem. Is there a way of exporting an easel project as a svg file?

What i’m overall trying to do is trace the image of a city skyline, create an inlay using the generator in easel, then reduce the cut from a complete “circular” cut path to just the line. This would reduce time of cut and prevent need for tabs.You can see what I was talking about in my original post in the images below.

Using easel’s inlay generator is nice because in creates perfect offset for the cuts… If I do editing in inkscape I’d have to generate the inlay in inkscape and that’s not quite as simple. It does it’s offsets in pixels not in mm or inches.

Thanks for the help,
Jim
