AoI The Angle of Incidence diff is shown in the wing view as triangle in millimeters if no ref is selected. Plus means faster. Minus means slower.
ref The current main/row or suspension point that is set as reference to calculate relative deviations. The referenced object is marked with a border.
You can select/change the ref by:
groups and rows Using the radio buttons () or click on the grey rows or names of the main lines in the wing at the top.
points Clicking the white area beneath the suspension point name
nom The nominal length between suspension point and main riser loop.
rdg The actual reading from your measurement device. When measuring, rdg is the input field.
diff The difference between nom and rdg. This value depends on the currently selected ref. If nothing is selected, the actual deviations from rdg to nom are displayed.
colors Areas marked in red color are further away (the line is longer) than the selected ref. Areas marked in blue color are closer (the line is shorter) than the selected ref.
status Color coded dots are shown for manual, imported & laser values
