Nothing!always says is not a member.
I found centre of the mesh using bouds and bouds.size (like x=bouds.x+bouds.size.x/2,  y=bouds.y+bouds.size.y/2  z=bouds.z+bouds.size.z/2) Is not the same thing?

But i need to find and move only the positions with the same coordinates in mesh1 and mesh2.
I will explain...

my mesh1 is a jaw and mesh2 is a tooth. If i move the tooth i need to stretch mesh1 moving the positions that, before moving the tooth, had the same coordinates.

I need to mantain the contact between mesh1 and mesh2 after moving the tooth.
I tried to :
1 - read all positions on mesh1 and check which have the same coordinates on mesh2, 
2- if yes marked them for moving, 
3 - calculate vector of mouvement (mesh2.center - mesh2.newcenter)
4 - move all the positions marked using this vector

Maybe it works but my mesh1 has 158000 vertices and code works 20 minutes!!

Some suggestions?
