This has been bothering me ever since I really got into Forge. I just cannot make any circular structures. So could someone give me a bit of advise on how to make good circles, mainly on Sandbox?
Place a circular hill or spawn area to the size you want in the place you want and use that as a guide. Also a lot of patience helps as circles can be tedious and annoying to create if you want to make it look good.
Ditto, i can't make circles for ****, i like to make triangular structures, as they're easier to make and look more Forerunner / halo-y
Use wide ramps when you are ghostmerging, that's easier than using a spawn zone (but the cirlce isn't that perfect) If you want it to be 'rounder', use wide ramps and huge wedges
Using Hills as guides is a good tip. Also, don't start at one point and then place its adjacent piece. Place your first piece, then place the second piece directly opposite. You now know where you're building from and building to. Then place pieces half way along the circle from those 2 pieces. You now have 4 points, you know they're in the right place and they're easiest to align because they're all at 90 to each other. I'd then keep placing pieces half way between the existing pieces, which are also not too bad for alignment. Use a Wall, Corner or a 45* ramp (on Sandbox) So you have 8 pieces of your circle all correctly placed. You may be able to do the rest by eye (still using the Hill technique)
A tin cup is a perfect circle. Anyways, you can also interlock four arches into a square to make a circle on the inside of them
