global change elevation

[youngEIT]

i have a bunch of contour lines that i need to lower by 1'. what would be the fastest way to go about it? they are in different layers (major, minor etc.). suggestions appreciated.

Hmm,

side or front view -> "move" with "_qselect"

Isolate the layers with the contours and move from 0,0,0 to 0,0,-1

make sure you do it "relative" - @0,0,0 to 0,0,-1
