title: Get the closest point on a surface - Maya - Python
body: <p>Could someone help me?
  How can I get the closest point on a surface form a locator in Maya using python OpenMaya?
  I was trying to use constraints but it has some snap that is not good for me.
  I would like to get the closest point, not the closest vertex. I want to get the nearest position from a locator even if it is at the center of a polygon. :)</p>
  <p>thanks a lot!!!</p>
