I'm in desperate need for a reliable Minecraft circle maker. I'm currently in need of one that won't lag me in insane amounts, mainly because of the fact that i need to make a circle with the diameter of 549x549, and none of the tools I've tried, including MSPaint, have helped. Anyone have any ideas?
You can mathematically deduce a pattern to make a circle YOURSELF. It shouldn't be too difficult once you learn a bit about how the minecraft circles work.
I have used a Mineconics site (http://www.mineconics.net/) when I wanted a circle. I don't build well so I messed it up anyway, but it wasn't the site at fault.
Is this for single player? If so, get worldedit. I have it and it is soooo easy to use. What I would do is get on the world you need it, do //hsphere (block ID or name you want) (diameter of the sphere). If I have it wrong, switch the two bubbled in phrases around. Then, just delete everything but the thickest part.
