I am designing turbine blade profile. One of the crucial parameter is the minimum distance between the lower surface and the upper surface of another blade (throat width). I have to keep track of it to ensure optimum blade performance. But the only way I know to measure minimum distance is by measuring tool. That means I have to click and measure it every time I adjust the arc length/radius of the profile components, which from start until finish can be up to tens or hundred of times. It is time-consuming and sometimes it hurt my wrist from moving the mouse so much. It would be great if I can have it displayed all the time. Is there any way to do that?
