Alternate wall direction changes window position

Aussie John — Wed, 24 May 2023 10:50:05 GMT

This has been bugging me for a while.
I am finding if i create a window the position changes depending on the wall direction (ie mirror the wall perpendicular to window.

Below is a script which mimics the structure of a composite wall. Placing it in a wall and making a mirror copy of the wall gives the result in the attached file.

I also find that if the wall is mirrored then the skin numbers work from the opposite side of the wall which is rather annoying.

Can anyone give me some hints here? thanks

!2D Script

row=1
add2 -a/2,0
for i=1 to wall_skins_number

skinF=wall_skins_params [row][1] !!skin fill
skinT=wall_skins_params [row][2] !!skin thickness

FILL skinF
poly2_ 5,3,
0,0,1,
a,0,0,
a,-skinT,1,
0,-skinT,0,
0,0,1

add2 0,-skinT
row=row+1

next i
del wall_skin_number
del 1

Hi John,

I think you have to use the "SYMB_MIRRORED "
and pay attention to
WIDO_ORIENTATION , SYMB_ROTANGLE
and other (see the Global/ general element Parameters)

ie.:
IF SYMB_MIRRORED THEN MUL2 1,-1

row=1
add2 -a/2,0
....
