Is there a way to control orientation of an

[Eric2575]

For instance: If I name a circle as pathA, a bowl (rivit) object as object to extrude onto pathA, can I control the orientation of the bowl/rivit object? I want the flat ends of the copied bowls/rivits to lie on the same plane as the pathA circle. See pic. Hope this description makes sense.

 

Also, is there an exact way to orient the view perpendicular to a plane that is not aligned to the x/y/z planes? I've been doing it by trial and error, but I need more precision.
