Autodesk Inventor

I swear I've done this before and now I can't make it work.

You can't copy a sheet within a drawing to duplicate it.  So, as a workaround, I saved a copy of the drawing to a different name and tried to copy a sheet back.  Pick the view in the browser, right click, copy.  Switch to the original drawing, right click paste in the browser.  All I keep getting is an error "Invalid input for Request."  I even think I remember getting this error before and finding a way around it.

So what am I doing wrong?

Im using Inv2012 from Plant design suite

I just tested...works ok for me...however view in newly created sheet neaded an update.

I tried it yet again by saving the existing drawing to "temp", deleting all the views, copying the sheet and pasting it into the original drawing.  I think there was at least a quit and restart of Inventor in there somewhere, too.  This time it worked.

Your drawing has to be saved...
