I have been playing around with Nanomesh and I think I must be missing something with the Const (Constant Height) setting. In the documentation it describes it as "keeps a constant height for the Nanomesh. I can’t seem to see this setting affecting anything when turned on. I had expected when this was turned on that all the meshes would have the same height. When fit or fill is on it does not keep the same height as I would have expected in the way the documentation explains. Am I misunderstanding what this button actually does?
