You need to either state the required plug-ins to open that file or internalize output from those components…

yeah, sorry. I dont know how to internalize output , so i will name plugins: lunchbox, intraLattice, Weaverbird and Pufferfish

That stil doesn’t help. There’s no input curve.

Right-click > Internalize data.

right click and press internalize so we have your data, or send rhino filwe with gh
