hey Perfecto,

I see what you mean!!! I had a similar problem with creating holes in a barrel as the extrusions/booleans etc always left a remnant 'lip'. I am greener than grass in all things Maya but I tried all different ways of achieving what you were after, with no joy.

The only thing I did which reduced the vert seam/crease was to grab the whole vertical row of vertices and shift them in slightly to the centre to give the 'illusion' of uniformity.

I think with my 'hole' problem ctbram said it pretty much is as you see it, unless you manually move them as you have done?

cheers bullet
