Hi, i've been working on site grading using corridor and custom assembly that involve conditional cut/fill for over a month now. The thing is, this is usually works until yesterday, and this happen. The feature line in the corridor seems to stop interpolating between 2 or more fill conditions, hence unable me to draw the corridor surface boundary. Do anyone know why this happened?
i attached the comparison between the correct and the false one, and also the assembly i use.
