TinSurface.Triangles

If I use a proper surface as an input and get this error as output, is this a node limitation? Bug? Or workflow limitation that I can’t input a “flat” area?

Thanks in advance for your guidance…

Hi @ddrennen2QDK2,

This node has not changed for many versions. Perhaps there is something strange with the surface itself, or the geometry scaling settings? Feel free to send the DWG if you want me to take a look.
