Scroll or pinch to zoom the diagram, click and drag to pan around.
Right click or long press on a square to highlight it and mark your place.
Have a look in the extras for stars (stellations) and other things.

FAQs
Due to the way rasterised geometry works, it makes a difference which direction you draw a line.
Because we expect regular polygons to have a certain amount of symmetry, I've made sure there is always symmetry where you'd expect.
Feel free to contact me
if you think something is actually going wrong though.
They are stellations -
star shapes made from joining the vertices in different orders.
Sure! Just send me your picture and the name of your build.
The more sides you have, the closer you get to having a circle. Also the shorter each side is,
the lower the definition, so it's harder to see the difference between your shape and a circle.
Email me your suggestion and I'll see what I can do.
I work on this site when I can but I am also a human who does other human things, so can't promise immediate updates.
Either make a thin shape then thicken it until you're happy, or build multiple thin shapes of different radii
with the same centre.
You can try, but you'll get irregular, nonsymmetrical, or imperfect polygons. Here, regularity and symmetry are guaranteed.
I've implemented all regular polygons, so you might just be missing it.
Try selecting "More sides" from the drop down, or see if you can find
what you're looking for in the "extras" bit.
Failing that, feel free to let me know which shape
you'd like to generate and I'll try to make it happen at some point.
This is as perfect as they're getting. Although this guy
tried to go one better.
Because the bresenham
algorithm (how we draw the lines) can give a subtly different result based on the direction from which the line is being drawn.
Send me a message and I'll do what I can to help.
It's really important to me that the site be as accessible as possible so no-one is excluded from using it, whether your issue
stems from an additional need or disability you have, or whether it's a technical matter of the diagram not rendering correctly on your device.
Yes! But only by placing the blocks manually. Currently this site doesn't support
creating minecraft commands or world downloads.
Of course not, this is just geometry. It's always nice to be credited though,
and it's lovely to hear when the site has helped someone.
Absolutely! The abilities to zoom and pan around the diagram (PixlMage), to highlight cells (TLS), to mark
the centre (SRP), to add an angle calculator (Katsu). These were all user suggestions.
I did lots of maths to find the vertices of a given polygon, then I implemented
Bresenham's line algorithm to draw lines between the vertices.
So people can make beautiful geometrical builds in minecraft.
