How to hollow a filled curve? I have the following curve (imported from an svg object):

and I want to extract the borders of it and ignore the faces.
I've tried converting it to mesh and deleting the faces in edit mode but that would delete the whole object.
Is it possible to hollow that object ? (It's possible to draw some beziers and match it to current curve's borders , but it seems too time-consuming for a complicated object).
Thanks.
Convert object to mesh > edit mode-edges > ALT + double click on the border to select all > shift+D to duplicate > P-separate by selection. You have the border without insides.
