When I try to make a region difference I get an error messange that says “No valid curves remained after projection in Group A” but I don’t see anything wrong with the curves.
These are the curves with which I want to use the component
But this is the result
I don’t know why it works with some curves but not with others.
Here is the file that makes the error
test.gh (15.0 KB)
I hope anyone can tell me why this happens
