I've been trying for a while to do this task that seem so simple.. I'm still learning Geometry Node so I apologies if the answer is pretty obvious. ^^
I have a bunch of faces, not attached, that I would like to scale along there own axis (relative to their Normal), perhaps using the scale elements node? Maybe there is a better node for that but this is the closest I could find although it's hard for me to get the correct nodes in the Axis input.
I manage to make it work somehow in both axis but it doesn't work for every face orientation :/
Any ideas for that?
