Hi everyone,

So I've been working on a dawrven city for almost a year now and I've started to use single player commands because its just not worth the tens of thousands of clicks any more haha. So I'm copying a map of a tower into my world its called "Tartaros" maybe you've heard of it. But there's a problem I know how to use copy and paste and I've mapped it out on where my two points are. But when I try to copy it I of course run out of memory... I'm working off a dell laptop with 8gb of ram and a 64 bit system. I'm not sure if this will help but my two coordinated are...

Bottom:
x=-196
y=1
z=-258

Top:
x=190
y=243
z=222

So does anyone know how to help me get more memory? I've tried editing my "player profile" but it fives me an error message every time I try. I've also tried shortening it all I can but no success, please any help would be very appreciated!
