NX Law Extension results are different depending on selection in structure tree or graphical area

Create a Law Extension (Type: Face) by selecting the Curve and the Face in the graphical display area and within selecting the Isocline Curve and the Face in the Structure Tree.

If performing a Deviation Gauge (Old-New Compare) and compare the "First Law Extension face" with the "Second Law Extension Face" you get a deviation of 0,01 mm.

Solution

If the inputs have some difference (like opposite curve direction, different start point when multiple input curves and so on) and the other parameters are same, there might (or not) be some little deviation between results.

Such deviation will be at most 2*G0-tolerance (suppose there is a theoretical surface and the 2 results have opposite G0-tolerance with such surface).
