Hi Fred, Hmm...it's a testament to the power of the ribbon diagram that many people don't even know that beta sheets aren't really flat, but for purposes of illustration, we often distort reality. It can be done in PyMOL, but you'll need to put some manual effort into it.
To do this in PyMOL, show both the flat sheet and the line or strick representation at the same time. Then put the mouse into editing mode, click Unpick (just in case), and then control-left-click-and-drag the CA atom until it sits in the beta sheet geometry. The CA-CB bond will seem a bit long, and the peptide geometry will get screwed up, but that's okay because next we hide the C,N,O (and H) atoms on the main chain, leaving only lines or sticks for the side chain, including the CA atom.
