I don't have a screen capture of this, but let's see if I can illustrate the problem.
I'm editing a TIN made from contours and spot shots. Sometimes I use the "connect nodes" tool from the TIN editing toolbar. I need help with the behavior of this tool.
Let's say I'm editing the TIN, and I want to connect node "A" to node "B", and node "C" to node "D". Sometimes it works fine as I click each node, A through D with connect nodes.
A---B
C---D
But sometimes, the tool behaves differently. I click each node, A through D, and a connection is also made between node "B" and "C", that I don't want.
A---B
/
/
C---D
If I click on a different tool, then back to connect nodes, I can avoid this unwanted third connection. But that gets a bit tedious. And sometimes, the tool works as I want it to, without the unwanted connection.
If I understood why the tool behaves differently in what appears to be identical situations, maybe I can compensate. But at this point, it seems random.
Thanks for any help.
