Hello Leo,
Thank you very much for adding another tip. I just learned about the Select Loop Inner Region function from you.
Unfortunately, I can’t apply it to this model without manually selecting the closed loop first.
However, this tip will be very helpful for other use cases, I will definitely use it so thank you again.

By the way, I saw your Chemex model from the Weekly Challenge.
It is so nice and realistic !!
Thanks for taking the time to answer my question!
