Excuse me, how to measure the radian and angle of arc glass on the handrail of arc wave glass stairs, thank you.

You need to make the total arc length of the glass, divide it into several pieces of glass evenly, draw lines on the original stairs, and then get several pieces of glass. Each piece of glass can measure the oblique length and arc length of a straight line, and the arch height of the center point of two points needs to be measured with a line. The angle of the glass is the height and width of the step. Be sure to pay attention to whether it is an inner arc or an outer arc. I hope I can help you.
