Can't close SubD

Hi community,

I’ve been trying to close the SubD geometry. I tried everything to fix it like the ShowEdge command, but saying it’s open SubD. Would you help me to close it?

your problem is here-

extract these faces, join them, flip the normals. then join back into the rest of the part. Add your creases as needed. see attached file.

one thing to note, there is a face here that needs to have a point added to change it to an Ngon.

then you can patch that face with 2 quads.
