Is this broken in 2014? can't seem to find the flip dimension toggle anymore. In fact, I don't see where flipping Angle and Distance went for individual edges. We used to be able to right click on the the edges in the collector and flip them individually.
When you are editing the feature, if you highlight one of the edge selections in the selection area it should put a pink arrow coming off that edge in the graphics area. Clicking on that arrow (or checking the box for Flip Direction) switches the direction for that edge only.
