HI Every one,

I am using "FeatureByPositionReverse" to get the feature which have to be the one after original point.

But I am not very sure the index of the original feature is "15". after traversing the feature tree, I found there are a few hidden thing before original point.

if it is a fixex index of every SW part, then I can easily lock the target .

pls help to advise.

regards

Vincent
