Is it my imagination or is the

"Converting  a Thin Solid Body into Sheet Metal and Surface Body"

lesson in the 'Static' tutorials completely messed up?

I have tried to work through this one a least a dozen times and at various points, the text of the lesson makes no sense or the software doesn't behave.

Furthermore, when meshing the 'SheetMetal_Study' the 'frame' component is deleted from the model.  I have to 'Undo' to get it to come back.  Why would simulation delete components from an assembly?
