Can't see sketch for models

So it’s late Friday I’m trying to get finished some parts I’ve laid out today and I have them all in one document to cut. I have everything nested and I’m doing to tool paths. I’ve done this … 10 times already… but for whatever reason, I can’t see the lines that mark where I need to make bends so they can be cut. The lines are in the underlying sketches but I can’t see them through the model… I solved this the last time I ran into it but now I can’t see it. can someone nudge me in the right direction?
