    Hello,

    I have the following geometry defined in free form. The alignment
    may look a tad funny, but that is just the font of my mail program.
    I believe everything that needs to be aligned is aligned correctly.
    (I have attached my .inp file just in case.)

    When I run with this geometry, I get many copies of this sort of
    error message from the geometry de-bugger:

       **** Lookdb: Geometry error found ****
       **** The point: 1.E-10 -5. 0.55 ****
       **** is contained in more than 1 region ****
       **** (regions: 4 R04CC00S 5 R05CC00W ) ****

    However, when I uncomment the RPP shapes above, and comment out the
    RCC shapes, everything appears to work well, and the geometry
    debugger provides no error messages. I believe the (free form)
    definitions of the RCC shapes I am using is correct. I could maybe
    understand if there were an error in both cases here, but only seeing
    this error for the RCC shapes has me puzzled.

    Does anyone know what might be causing this sort of error? Thanks!
