basically this is a sanity plea.

I can't seem to get my head around this tool.
It doesn't seem to behave as I'd expect.


Does anyone have either a clear explaination
on how/what this tool's function actually is..?

Do the edges have to exist on the same
poly object?
Is this suppose to act as a weld?
How "close" do the edges have to be?
Is this to be (always?) to be used with
"poly->combine" ?

TIA -TH
