I was wondering if there is a simple way to create a large circle or circular plates. I want to build a MOC of the Hero Factory assembly tower (In LDD first) but most of the pieces that form circles don't give enough clearance for a decently sized CCBS model. I was wondering if there were any bricks or techniques that would help for this specific MOC.

    TL;DR: How to make a big circle-shaped PLATE, right?

    ...and if so, HOW big a platform? what's 'decently sized' mean? just some rough figure, any unit will do...

    @Uli when I said "decently sized" I was thinking around a size to fit a set like Breez: 2227 or Surge: 44008 positioned to take up as much space as possible space since I want to treat this like an easel but for creating CCBS sets. Commented Jun 8, 2020 at 21:24

1 Answer 1


The largest truely round base plates in the LEGO system fit in a 8x8 square. You can build them from two LegoPlate, Round Half 4 x 8 or from four quarters.

For a bigger (and thicker!) base plate there is a Duplo version of the above mentioned base plate, fitting into a 16x16 studs LEGO system square: LegoDuplo, Plate Round Corner 4 x 8 Double

EDIT: For a thicker base, you can use these bricks: Brick, Round Corner 10 x 10 with Slope 33 Edge. They make a base fitting into a 20x20 square.

  • @molot Nice finding. I wonder how round this brick is, it seems¹ that for 4 studs it is just straight before the round contour starts. ¹I don't have one of them in my collection Commented Jun 4, 2020 at 14:48
  • I don't have one either, so let's just leave it in comment for now, maybe someone else will be able to tell. Another question is, how round @medicinalman really needs it to be.
