Since (-1, -1) is the mirror of (1,1), I use REFP -1 according to AQUA manual pp3-180, and it works.
REF -PTY Mirroring to a point
Since (1, -1) is the mirror of (1,1) about y-axis, I tried to use REFP 1 -1, according to AQUA manual pp3-180
REF PTY -PTY Mirroring to the y-axis
VERT | NO | Y | Z | REFP |

3 | 0 | 0 | 1 -1 |
But it does’t work. How to fix it by using mirror about y-axis?
