gw.setTransform(Matrix3 1)
gw.wTransPoint $.transform.row4

I do not undertand gw very well . But this codes above works well for me.

see this post (http://forums.cgsociety.org/showpost.php?p=5353613&postcount=12) from i thread I started on the same topic some time ago. dont forget to use gw.setTransform (matrix3 1) before calling gw.wTranspoint()
