excluding Points with specific ID from group

[F10]

Hello all,

I've got a rookie question, probably straight forward, I'm trying to select points which are not in a specified group with a nearpoint function (I'm getting the same result with pcfind and nearpoints).

I've got a series of point 'growing' in a solver creating lines. I've set an integer attribute 'source' before the solver so each connected points have the same source number. Then I need to select the closest point which is not part of the same line when these lines intersect. I've found out that :

 string grp = "!" + itoa(i@source);

should do the trick but it doesnt some how.

I'm missing something here, I'm sure it's straight forward, anyone has any idea?

 

Thanks a lot! cheers
