Hello Marco,

if you want to use sweep it is also useful to evaluate the startFrame of the railcurve for profile placement. You will find a node for that in infonodes. To get it run you have to replace the pushFrame function in litegraph.js with the posted in this thread. What I am think about at the moment is to put such meta informations like startframes of curves, boundingboxes, curve length, mass, ... in a functions container. Max has already made a addOutput-function. I think it would be better to put such functions as additional outputs to nodes, than create separate nodes for it. Unfortunateli are my programming skill are very limited and I can't find a node with an addOutput as a template to study. Maybe Max have one?
A nice weekend to all
