Minecraft /fill command

[StardustGreen]

Hello everyone.  I'm currently running a Tekkit server, and I'm wanting to use the /fill x y z command to fill in a large area of blocks to start building on.  It currently works on the latest version of vanilla minecraft, but does not work on the Tekkit server I am currently running. Does anyone know of any ways to do this?  This is not related to the filler machine.

 

Thanks

The /fill command was not introduced until Vanilla MC 1.8. Tekkit is currently 1.6.4. Two ways to fill an area is with a BC filler or by using WorldEdit.
