Select by Z Height

Hi!

I’m working, at the moment, on a heavy topography that has several countor lines. Unfortunatly, in some locations they are not connected and can’t be. The countor lines are 1m apart. I would like to select them by increments, 2m apart from each other counting with 0 to the last one on the top.

I’ve come up with this but doesn’t work whenever I have more than one curve at the same level. I don’t really know how to set up the Z vector in order to select them by height. This is a test file in order to make it simpler to see and work.

Thanks!

Attach the file and you might get some bites!

Hi! I figure it out this morning, thanks anyways!
