Project curve on surface distorted!

This should be pretty straight forward but I cant seem to get the result im after. Im modelling a phone in Nurbs and want to trim out some button holes in the surface. Ive created a periodic curve that I project on the surface and while this works the resulting projected curve is distorted??

This is not a tessellation display type issue. as once i do the trim the surface renders the same way. Im surprised maya doesnt seem to be able to retain the shape of the original curve. Ive played with the tolerance setting but to no avail.

What am I missing here?
Can anyone shed some light on the subject?

I did test the curve projection on a nurbs plane with lots of divisions in U and V which did give me a more accurate projected curve but it still wasnt correct.

Would appreciate any thoughts, google doesnt provide much in the way of answers as all examples are generally simple shapes.

Thanks

EDIT
**
Solution. I was modeling the phone at 1:1 scale. Seems Maya does have issues trimming surfaces under 1 unit in length (a small button). Scaling things up then doing the projection/trim gives much better results. Especially considering the tolerance setting was already at 0.001.

Hope this helps someone else.
