Close holes possible?

Hi dear community,

Is it possible to close (large) holes in the meshed model? Unfortunately, I haven’t found an useful command yet. Therefore, my question is weather such a command does exist for open3d or not. My goal is to determine the volume (float) of the meshed model. Is open3d appropriate to do this job? I would appreciate any help or advise regarding how I could proceed.

Thank you in advance!
