Hi Barry, Had a play with it I get to select the curve but geometry doesnt build I am running editor 1.1 is this the correct current version? from the wiki seems I am up to date. Also one comment on the node is with the script you can select an entire group of curves and they all populate at once - this is how weldments on Solidworks and other programs work in a similar fashion could this be possible also - selecting a group of curves.
