Cv World Scale Coordinates Attribute

Maya
1

I need to connect the CVs of two identical polygonal meshes.
The position of the CVs must be the same in world space.
But the CVs attribute (pnts) is in local space.

I can't use a xform in a connection, can I?
Is there another attribute not listed in the doc (I'm on Maya 7.0) that gives the worldscale position?
Do you have any suggestions?

Thanks

There is a xform node its called transformGeometry, which is cool for number of thing such as veird camera projections (but for some reason it transforms ploys as if their points had a null row as zero instead of one so you can't do perspective transform with it on polys), or just plain countermoving the transform so thet you can free up manipulator axes for something other than manipulation (now this means you coul ddetach parts of the skinned mesh and use them to drive the bones, yes)

Quite useful node. Thanks
I didn't understand your note on points that have null row as zero instead of one.
What does that mean?

its a affine matrix thing.

search for point versus vector transformation.
