How to pick up interior surfaces of one part?

[Bigtree]

Hi, how can we pick up interior surfaces or lines after we partitioned one part?

There is an option for selecting surfaces so that you can cycle through all the nearest surfaces to the pointer on the screen until you reach the one you want.

There's also a filter (use the right mouse button "Selection Options") that allows only interior entity picking.
