Hi! Can someone please share some thoughts about the considerations and heuristics that one would use to find the valid surface curves. In the data there are many prominent curves that are not being considered surface curves. I am sharing an example. What's the criteria?

There is ignore mask. I was only visualizing the surface curves in that image.\nWhy is that area being labeled as ignore while there seem to be clear surface curves?
