How do I creeate a 104x104 1 block thick square?

[Beavermon]

i've been trying to //pos1 //pos2 the coords then /fill it with dirt but it just makes a huge cube

Fill isn't affected by the selected positions. Read the Readme on what the command is actually doing.

I'm still confused, what does it mean by direction?

[platz1de]

you are looking for //set
