 gw.setTransform(Matrix3 1)
[b][b]gw[/b][/b].[b][b]wTransPoint[/b][/b] $.transform.row4

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

see this post from i thread I started on the same topic some time ago. dont forget to use gw.setTransform (matrix3 1) before calling gw.wTranspoint()
