This is a quick example of how useful the ‘copy’ of a level can be as it will automatically update when the original is changed.
I’ve done some more sophisticated applications of this but this is a simple translation to the right and left in order to get repetition. The red lines are tinted so that I know which ones are the originals and can easily add to them (rather than adding via the copies which may result in lines being drawn where we don’t want them.
The finished product in almost all cases would break up these patterns in appropriate ways.
Duplication can also be accomplished within the schematic view but that isn’t as responsive as directly drawing onto the canvas and seeing those lines automatically repeat.
