Let's say I have at least 3 Layers. I want to reshape a polygon of layer 1, tracing a polygon from layer 2.
This is no problem if you have only those 2 layers. But now I need layer 3 (or 3 to 10) turned on for information when tracing layer 2. What can I do that the trace tool only traces layer 2? I know what to do when I create a new polygon (then I just select the polygon of layer 2 and set the trace tool to "trace selected features only"). But when I want to rehape the polygon of layer 1 I don't know what I can do.
I want trace only on the red lines. Does anyone know an answer?
