Select is used to select members of a group or list. I assume you have a field that is composed of positions, connections and data components.
Are the connections irregular too, i.e., do you have an explicit connections list? If so, Slab won't work. Slab works on positions indices, assuming regular connections, although positions can be irregular (e.g., a curvilinear grid). However, you can use Include to operate on the positions: | Mark (,"positions") | Include -- specify a min/max range for x,y,z in the position values not the indices | Unmark | This can also work on connections. If you know how the ordering in your connections list corresponds to the indices that you want to keep or eliminate, then multiple Includes between Mark(,"connections") and Unmark might do the trick.

Is something possible with Select and then creating 'Invalid Connections'?
