I have a really simple question.. Something most of you all know, probably..

In the schematics for the Equipment Factory and the Small houses it says 'Similar Wall Module items' Does this mean they have to be exact? I know some houses have to have identical Wall Module items, but since I just got Novice, I'm not sure if it says 'identical' in the schematic.

So what I'm wondering is if I can make those few 'similar' wall modules by hand for the small houses and factory or do I have to buy them from another achitect that uses a factory?

Thanks in advance.

Just pretend the word similar isn't there. Anything that says similar wall modules or whatever just means wall modules. They don't need to be made from the same materials or even by the same person.

Thank you!
