Sheetmetal in WF2 - extrude an attached wall?

Can I still extrude an attached wall?
It seems that the old extrude icon has been replace with Flange.
Then I looked in the icons under the sheetmetal toolbar and the old
extrude is there but greyed out. I drag it up and it says it's added
and that it will be shown at the proper time.

But it doesn't show up when I go back to my model.
I have an extruded first wall with 1" vertical flanges,
so basically a really wide U like this >>>> |_____|.

I want to add walls on the ends, "closing it off" and making it
have 4 walls.

I saw the functionality of WF2 sheetmetal and was excited.
I also thought I was pretty good at shheetmetal until WF2.

Any ideas? Running WF2 build M080.

Thanks

Mike

"Summary

The Flange Wall feature consolidates and simplifies the creation of

sheetmetal extruded, swept, and hem walls.

Benefits and Description

This feature offers the quickest and easiest way to create flange walls along

an edge on a sheetmetal part using the object-action and action-object

paradigm. It comes with industry-standard, predefined shapes for the walls.

You can define your own section using standard Pro/ENGINEER sections.

Direct manipulation of all standard shapes and types of wall relief is

available through handles. Wherever necessary, automatic wall relief is

added.

Using the dashboard, you can flip the thickness of the sections. There are no

constraints in the selection of the edge from which to generate any wall."
