After a Sandbox from contour
How to kill all faces inside the internal circle ? (or the inverse how to select faces from the inverse of the internal circle? )
(except kill one by one)
red faces are the "blue inverse":)Here the internal, external circle can always be selected
-
left right select center part (it is possible--no radiating edges or far outside edges). Group. Delete.

@ Rich : not fair it's $ plugin
@ pbacot : sorry I don't understand
Ah yes a box selection ?
-
To kill you must pay.
Or Artisan Brush select. Set radius to inner ring. Click and kill.
Only the great plugins are $
-
Or swipe the erase tool through that mess a couple times while holding down the "ALT" key.
-
In fact I just find!
A simple box selection from left to right with a good first point clicked! (up left on the disc) 
It's the Pbacot answer that I don't understand who gives me the key
Many Thx to him
I had tested numerous solutions except this simple one!

I don't see how this works. All you can select is vertices and you loose the outer ring.
Make it harder.

I'm trying to learn video recording but by the time I manage one, you'll have figured it out.

Works for me. But I did leave out some info
If you wanna do a quick screen capture with audio or without try screenr.com

@ Roger: Valuable on a little surface and with many zoom!

Turn off hidden geometry. By double clicking face to select face and outer edges, then shift-click (deselect) face, you choose only outer edges. Offset tool. Offset outer edges to inner ring (SU snaps to hidden edge). May have to do this twice to get a hard inner ring edge. Select all. Shift and double click outer face to deselect. Erase. Native tools.
You don't have to buy tool (but it's REALLY worth it).
OK Rich I see, exit the tool. Thanks, Peter

16 seconds : that's a task

Your last solution gives me another one
because your Offset tool seems don't snap on Outer "Vertext" or middle of segment circle!
bug ?
just snap on the inner circle at the end
So difficult to fit the 2 circlesSo Top View
Turn off Hidden geometry
draw a circle from the Center to the inner cirle (you must know the number of sides circle of course
Double click on the disk between inner and outer circle
Invert selection (By TIG)
Erase -

EraseWorks OK for me to use the offset tool--but this is if the original ring is an exact offset. I don't try to snap anything. Just move in and it finds the snap. For some reason I had to do it twice sometimes.
Rich, Maybe I'll try Screenr-- it starts out by requiring me to update system software because it doesn't recognize my java. So it'll be hours.
OK I figured the screencast out. Not that great because I should have given audio. But my first screencast! Thanks Rich!

I always use 'cut' >> 'paste in place' for this type of selection.
Select 'contours' >> 'Sanbox' from contours >> Select 'contours' [not new group] >> 'Cut' >> 'Edit' group >> 'Paste in Place' >> Select 'surface' between contours >> 'Cut' >> 'Select All' >> 'Delete' >> 'Paste in Place'.... Done

A little tricky but works like a charm!
-
Something a bit like what driven said..
Select contours...Copy it...use sand box tool...edit created terrain...paste in place contours and then delete unwanted faces is really easy as all edges are soften except the contours you pasted in place...(make sure hidden geometry not visible of course !).
Cheers.

Seems with this last solution the erase don't works in one click!
Some little faces stay so you must make some clicks more
