How to replace all non-air blocks in an area

The "Check for block in 6x6x6 cube" procedure template has the loop setup required to check all blacks in an area, you can then change the part that checks if the block at the modified location is a certain block and replace it with "not""is air at X Y Z" but switch the X, Y, Z to X+sx, Y+sy, Z+sz.

Also change it so that instead of setting found to true, it places the block you want at X+sx, Y+sy, Z+sz, but in the same if block as the set found to true.

One more thing, remove the empty if found equals true loop, as you don't need it.

Also, I will not send an image of the procedure as I do not use image hosting websites.
