Hi all,

I'm following along with the "Learning Maya 2" book (PDF) with Maya 4. However, I'm now working with NURBS and the interface seems to have changed quite a bit...especially the layer bar. I'm stuck on "Creating the Top Surface" of Lesson 7 on page 136.

I'm trying to create the top surface of a NURBS box by adding two different layers and adding the base surface to one layer and selecting the top edge isoparm and then duplicating it using "Edit Curves" -> "Duplicate Surface Curves".
When I try and add this selection to the other layer I get: -

Error: Only DAG objects can be in a display layer. 'curveFromSurfaceIso1' ignored.

Yet in the book, it seems to work fine. Any ideas?

Jon.
