Trim curves: some work, some don't

Here's the setup. The surface to trim is a truncated cone. An elipse is
sketched on the same plane as the sketch of the revolve. Toward one side the
elipse is projected, toward the other it's wrapped. The projected curve
trims the surface just dandy but the wrapped curve won't even select to
create the trim. In both cases, select the surface first, which puts it in
the trim quilt box, expecting the selection of a trim curve or some other
trimming object. Other than not being able to trim the surface with the
wrapped curve, the new trim tool is very versatile. Seemed to me you could
do this at one time. Buggy software?

Multiple attempts with old and new models (my example was new), but all with
the same result.\

Other wierdness: when trying to pick the wrapped curve, it acted like two
separate halves, but I couldn't pick both segments. So, I thought, why not
make a composite (copied) curve. Couldn't even do that. Selected the wrapped
curve, did ^C, deselect, ^V and it brought up a strange interface where it
was looking for a sketch and solid geometry.

My only conclusion, so far, is that Wrap wasn't meant to drape closed loop
curves on a surface. I don't know what else to make of it.

Yes and no. I got a closed sketch to trim a surface with a wrapped curve.
But it was composed of multiple entitities, not the single curve of the
elipse. I was thinking to try it when I got back to the office. I've got a
later version of WF2 there. Might make a difference.
