Question about mirroring point on section in AQUA

I want to define 3 points (1,1), (-1, -1), (1,-1)

+PROG AQUA
HEAD
CTRL FACE NEG
UNIT 5 DIG 3 SET OUT
ECHO SECT EXTR
NORM GB 50010-2010
STEE NO TYPE CLAS
1 S 345
SECT 1
POLY TYPE MNO
O 1
VERT NO Y Z REFP
1 1 1
2 0 0 -1
3 1 -1
END

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
1 1 1
2 0 0 -1
3 0 0 1 -1

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

Hello

The program doesn’t know which item the value ‘-1’ belongs to. So please add the item ‘REFD’ to the first line of the table.
