Pick up local coordinates

Complex UV Layout in Maya

Over the last couple of years UV layout in Maya has changed for the better. In this course we're going to be taking a look at some of those changes as we UV map an entire character

Hello,

I've placed a locator in relation to an object of my scene (this object has its own coordinate system) and I would like to know how to pick up the coordinates of this object in the local coordinate system (not world coordinates).

I want to do that because I want then use these coordinates in a MEL program to place the locator in relation to the object whatever the position of the object is in the scene...

Thank you

EDIT : Orthography...

The center of the poly primitives is 0,0,0, but this will be reletive to the world co-ords with its origin on 0,0,0.

So if a cube 5,5,5 will have is local origin at 0,0,0 but in world it would be at 0,2.5,0. How to get MEL to pick this up would be getting the co-ords of the vertices. The cube would have 8 verts 4 top and 4 bottom each occupying its own space.

Enough theory... Have a look at this link:
