How to Make a Spiral Staircase in 4 Steps
1. Create a room with a column, and then subtract a column from this (remember where you put the centre column)
2. Start subtracting blocks all the way round, you'll have to work out how many steps per cycle and where each step goes. If you assume it's a square (split into a 3x3 grid), with a square in the middle, I create blocks for the 8 surronding squares moving up each sqaure.
3. Keep moving the cursor up as you go round, take your time, it's easy to make a mistake.
4. Once you've got to the height you want, create a union column the same size and position as the original centre one.
And the final Product...
