Newbie here. I want to do a Polyfill and I got the “Some patches were not created because they were degenerate or on non-manifold geometry.” message. I encounter that problem many times before and I always managed to do a workaround. I would like to know how to fix it or why it appeared in first place so I can avoid it in the future.
Attached there is a simple hip file with the issue.
Thank you for your reply. Im new to 3d modelling and I din't know about those kind of issues. If somebody else run into the same issue, it's called “T-type”. The solution it's either to give it more volume or to delete a face.
