Hi,
As pointed in another thread I'm using Points2One on the output of a tacheometer to connect automagically the survey points. Recently has been added the possibility to group the features using an input field, my problem is that it only groups these features if the chosen input field's values are strictly sequential : if a feature B is between two sequences of the feature A then those 2 sequences become 2 different polygons instead of one (A:1/2/3, B:3/4/5, A:6/7/8 instead of A:1/2/3/6/7/8).

1 0996 515 8,2 A
2 0998 515 8,2 A
3 1009 504 8,2 B
4 1010 504 8,2 B
5 1010 504 8,2 B
6 0996 515 8,2 A
7 0998 515 8,2 A
8 0999 515 8,2 A
It would be great if the plugin could parse the file, group the feature points sequentially by the input field and only then draw the polygon as it would allows a surveyer to stop collecting a long feature to collect a small nearby feature and then resume on the previous one.
