I don’t know how you did that, but “Box Corners” doesn’t work with Twisted Box objects.
(actually i’ve found very little info about Twisted Boxes…)
“R” input of “Morp” component need a normal Box as input, not a Twisted Box.
Also, you did feed a list of X and Y to “Twisted Box Curve” component, resulting in 196 twisted boxes… use a single value.
The only way i’ve found to re-arrange Twisted Box corners is to pass through DeBrep and make a new one.
Probably it would have worked also by using a different “R” box, making it from a different plane/system (like XZ or YZ or such…).
