How to partition parts on 3DExperience platform?

Hello!
I partially know the answer to this question, but I wonder how users typically approach geometry partitioning on 3DX. Having Abaqus background biases heavily my way of geometry preparation process so I wonder what would be your best tips on how to partition parts.

Obviously there is the partition tool, but it is not always giving the results I expect. There is also the automatic partition tool, but I often like to perform some manual changes.

Thanks for any pointers!
