Hi guys,

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.

Thanks,
Juan

You have three faces sharing an edge, which is non manifold geometry. That is your problem.

Hi

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.

Thanks again,
Juan
