Why such poor results with Background Erase?

[Contours]

Here is a video that may help.

Actually, I had watched that very video before I made my post. It does give a good result, but the page I referenced certainly gave me the impression that a few "identifying swaths" were all that's needed ... and the software would do the rest.

Rather than try "detailed swaths", I'd much rather outline the object and be certain of what I'll get.

I was just expecting more from Xara.

Thanks for responding.
