Hi, I have a GMS modflow model with multiple layers (9 layers). I used about 200 observed heads for calibration. These observed head values are in different layers. I want to check how successful the calibration is in each layer. Currently, all observed heads are visible and it is hard to recognize what head is at what layer. Is there a way that I can see the observed heads that are in a selected layer only? I tried orthogonal mode on but it still shows all observed heads regardless of the active layer in orthogonal mode. This model is in GMS version 9.0. Thank you, Lalith
