Thank you for the reply!

If I assign a parallel axis, doesn’t that only give me the height difference of the top end of the line and ignore the fact that the edge is curving to the right?

Sorry, I probably should have been more specific with my question. The problem is that my original geometry is not a straight line but curves around a cylinder, so I can’t assign a parellel axis. It’s supposed to simulate a strain gauge but I’m not interested in the strain, only in how much the line deforms.
