Ahh thanks both! That's perfect!
I came close to your method mestela but got confused when the resample copied my attribute to all the new points and missed the all important attribtransfer step!

Tamte> wow. That's truly elegant!

I have a curve with a few points, (group1)
I resample the curve using the resample by polygon edge setting and a fixed distance between points, (group2)

I would now like to delete those points which were in the original curve.
Since each line section of the curve may be a different length, there doesn't seem to be an expression I can use to group and delete these points.

Please someone tell me how can I delete the points from group2 which are also in group1? I can't figure how to do this with the delete, group or blast nodes but I feel I'm overlooking something simple..

thanks all!

Wow, that's spot on! thanks mestela!
