Ok so i want to make a little house on top of the Rivet city flight deck (were all the planes are on the boat) and I cant find the cell any were can anyone please help me out on how to find it

waht do you mean you can't find the cells anywhere? how are you trying to locate them?

RivetCityExterior08 [CELL:00000DAF] (in Wasteland "Wasteland" [WRLD:0000003C] at 18,-17)

Remember when you load up the geck you need to navigate to the 'wasteland' sub grouping of exteriors cells. All exterior cells are grouped by location/function eg megatonworld, testworld etc you need to find 'wasteland' (its near the end of the list). Once you are in the wasteland subgrouping scroll down to RivetCityExterior.

i some times find it easier to use a interior door marker to take me to exteriors rather than serching for one if you dont know its cell name
