What can I say?! Bruce, that was some black magic. I don't quite understand why asking it to ignore a leg then changing your mind and asking it to draw it anyway, would cause it to then split it at the point you want. I wonder if I will be able to make sense out of that in future.
What is makes me wonder is; why doesn't this exist? extend break 6 This could cause a centreline "weakness", and prefer (but not mandate) breaking at that point. It would massively simplify this control, and be much more predictable. > try to change the line in your .th file from: > > extend ignore 6 5 > > to: > > extend ignore 5 6 > > There is no leg 6-5 in your data, but there is leg 5-6. This does not work. I assume that is because it is trying to extend the centreline from left to right, so it steps backwards through that oxbow (compared with the data). Or maybe I have not played with Bruce's solution enough... Cheers!
