Absent a 1-2, got a semi slick work around solution for the even distancing problem in ID editor. Draw a 2 point line from last to first bollard in as row, then find the automatic triangle mark middle point on the line (don't know what the official name ref. is) and drag it to the third bollard from any side on the sat.image. New triangle grip points are generated. Rinse and repeat. Each time a point is added half way a line section, neatly in middle, e voila, nicely spaced bollards that can be added to these point. points. Since the bollards are interconnected with a chain, converted the line to it's appr.identifier. On even, the last point is eyeball.
Why do it the easy way, when there's a hard day's night.
