HI Michael
一个冒昧的请求：能否将CurveLengthBeingDrawn的代码改为将长度信息以弹出信息面板的方式呈现的脚本呢？或者能告诉我怎么做么？十分感谢！（A bold request: Could you please change the code for CurveLengthBeingDrawn to a script that presents length information in the form of a pop-up information panel? Or can you tell me how to do it? Thank you very much.）
