Hi Jochen,

We are working on closing some loops and we are struggling a bit. I think we now understand how to set them up, but if there is a mistake in the sign ( + or - error.), I find it very difficult to track down the error(s).
I see the loop configuration as configuring a river flowing from the point to loop back to the point to loop via the surveyshoots... clockwise or anticlockwise , your choice. If a shoot direction goes against the flow, then it has to be negative, if it goes with the flow then it is positive. Something that would be great to assess the possible error on sign would be to display the survey shoot direction with an arrow, which would be reversed if the sign is negative. this way the "flow" could be assess and sign error easily detected. see drawing attached.

Also, if this was possible, it would be good to be able to change the sign on the chart using right clic (same way direction is changed), instead of chasing each shot in the data table.

Not sure why it doesn't pop in... I sent it to you via PM
