Utkarsh, How about a "Freeze Selection" choice like in Find Data that would convert a frustrum selection into an ID-based selection which would enable the use of Add Selection using another frustrum or any of the other Selection tools.

An implementation nuance, and no one asked for it :). The extract filter just support extracting a single frustum. We, in theory can make it support multiple additive frustums, but some additive, some subtractive will make it a trickier implementation. Of course, doable, not since no one asked for it, it never got around to getting implemented. > Should Select Block be divided into “Select Block Cells” and “Select > Block Points” Good idea. > so that this selection method could be combined with Select > Cells/Points On/Through with the “Add Selection” to finetune a selection. > Alternately should “Select Block” be smarter and only select Block > Cells if the current Selection is Cells, or only select Block Points > if the current Selection is Points (and add them to the existing > selection instead of replacing it? Ah! That's cool and not easily supportable the way things are currently. But Berk and I were chatting and we have an approach to support combining multiple selections add/remove/etc. nicely. Now just convince Alan to make it a priority and I'd love to have it sorted out for the SC release ;).
