Sweep-error - mis-numbered profile vertices

Hi All,

I am trying to work with a sweep component and I am getting some undesired resulting geometry.

I have found the problem which is the numbered vertices of the profile I want to sweep...
attached is a screen shot of what I am describing...

you can see that in some cases the sweep gets twisted because it is trying to connect the same vertices numbers...

does anyone have any idea how to re-number the vertices in a profile...or any ideas of how to re-adjust them for the purposes of a sweep?
any ideas would be really great...

Thanks

M.
