I have a problem made up of multiple surfaces. Some of those surfaces have holes I need to close using a merge. The tree level of the boundaries differs from the openings. I have tried to manipulate the data in many different ways (split/flatten/trim), and I am not having success. I believe I have the data tree structure correct, but the merge does not close the surfaces into 6 surfaces. Suggestions?
Thank you for the clear explanation. I thought it might be my data manipulation. It seems critical to check the data tree with each operation. I was testing different cases this am, and I had to go back a ways to find the cause of my problem.
