I would love to see a "plane slicing tool" that splits a model into 2 objects. This can be shown as a sharp knife metaphor to make it easier for users to understand. Today it is possible to do this but involves duplicating the object and creating 2 adjacent hole cubes. Too many operations. Also the model is saved with excessive data. Ideally, the knife could be also configured with part fitting profiles so they can be reunited in the physical world. I would be happy with only a plane though. thanks for listening.
