@Bruno_E1 Could you upload a file showing that issue where _Reflect creates a hole in an otherwise regular quad layout? That looks like a bug to me but I haven’t been able to reproduce it here from a SubD plane.
If your file needs to stay out of public forums you can send it via email to pierre@mcneel.com or using the form there: Rhino - Upload to Support
