@Jaceen No, exactly the other way around. Void blocks are used to mark parts of my structure where I don't want to place any block and keep whatever block there was previously.
A good example of this would be a circular structure. Structures are always rectangular, but by filling the corners with void blocks I can tell Minecraft that this part of the structure should be ignored and only the circular part in the middle should be generated.
This works fine as long as the structure is placed by a structure block (using "load"), but whenever moment the structure is placed by Minecraft's world generator void blocks are set (even though they should be ignored) and air blocks are ignored (even though they should be set; preferable as CAVE AIR blocks so they can no longer be overriden by other parts of world gen).
