Have often thought that it would be nice to be able to cut a piece out of an object either to paste back into the object, to stretch and modify a section, or simply to remove an unwanted section. This comes up most frequently after importing an existing STL file. In short I am looking for a better alternative to copying the object and adding one or more "hole" objects and grouping them to remove the unwanted portions. I think the best way to implement such a feature is to use the existing concepts for hole objects and add a third option of select . This would work by identifying intersections of the select area and then allow copying and cutting of just that intersected region.
