Not sure why the consturcted plane is null, seems very simple ghq_Why constructed plan is null.gh (8.3 KB)
Check the difference. If you don’t provide the Y-Axis vector, your X and Y Axises are identical, that’s why the Null plane…
Or…
Hello @HS_Kim ,
I think I have a similar problem. If I don’t connect the Y value I get null values for the top curve. The workaround I tried to imply didn’t do the trick unfortunately. I can’t think of a solution. Any help is appreciated!

Hello
you just have to use another cross vector of X plane direction with World Z vector, so you will have a perpendicular vector to feed in Y plane vector.
