So... can this feature be turned off?
don't find it useful....
I only see that when I dimension the line and select the end point, then the arrow shows for an angular dimension. Are you seeing it somewhere else.
Your description of it's occurrence is corrected - my ignorance was in using it - I have since figured what it is for, however it seems a bit of a faff trying to use it - hence wanting to turn it off!
It appears when you select a line and a vertex on the same line, since SW15. Looks like you can not switch off that behavior.
