I am trying to follow the steps indicated in this discussion How to interrupt contour lines beneath elevation labels (instead of using label buffers)? but I have some problems.
I created the contour lines file by the v.split.length and I add a 1 digit integer field called showLabel in the attribute table of the layer.
Now, there is someone who can explain to me, step by step, how I have to continue? The steps indicated in that discussion have not been clear enough for me.
