Hello All,
How about this as a solution:
1. Stroke the original path
- You should now have a stroke line on the inside and outside of your path.
2. Now select Path - Break Apart
3. Now if you select your outer most stroke and drag it to one side you should have a completely filled stroke of your original path. (Hope that makes sense)
4. Now turn off your fill
5. You should be left with a stroke in the shape of your original path. (At least the outside of it.)
Hope that makes sense and hope it helps. I made a little video showing this:
